-# Contributing
-
-Welcome stranger!
-
-If you have come here to learn how to contribute to mdBook, we have some tips for you!
-
-First of all, don't hesitate to ask questions!
-Use the [issue tracker](https://github.com/rust-lang/mdBook/issues), no question is too simple.
-
-### Issue assignment
-
-**:warning: Important :warning:**
-
-Before working on pull request, please ping us on the corresponding issue.
-The current PR backlog is beyond what we can process at this time.
-Only issues that have an [`E-Help-wanted`](https://github.com/rust-lang/mdBook/labels/E-Help-wanted) or [`Feature accepted`](https://github.com/rust-lang/mdBook/labels/Feature%20accepted) label will likely receive reviews.
-If there isn't already an open issue for what you want to work on, please open one first to see if it is something we would be available to review.
-
-### Issues to work on
-
-If you are starting out, you might be interested in the
-[E-Easy issues](https://github.com/rust-lang/mdBook/issues?q=is%3Aopen+is%3Aissue+label%3AE-Easy).
-Those are issues that are considered more straightforward for beginners to Rust or the codebase itself.
-These issues can be a good launching pad for more involved issues.
-Easy tasks for a first time contribution include documentation improvements, new tests, examples, updating dependencies, etc.
-
-If you come from a web development background, you might be interested in issues related to web technologies tagged
-[A-JavaScript](https://github.com/rust-lang/mdBook/issues?q=is%3Aopen+is%3Aissue+label%3AA-JavaScript),
-[A-Style](https://github.com/rust-lang/mdBook/issues?q=is%3Aopen+is%3Aissue+label%3AA-Style),
-[A-HTML](https://github.com/rust-lang/mdBook/issues?q=is%3Aopen+is%3Aissue+label%3AA-HTML) or
-[A-Mobile](https://github.com/rust-lang/mdBook/issues?q=is%3Aopen+is%3Aissue+label%3AA-Mobile).
-
-When you decide you want to work on a specific issue, and it isn't already assigned to someone else, assign the issue to yourself by leaving a comment with the text `@rustbot claim`.
-Again, do not hesitate to ask questions. We will gladly mentor anyone that want to tackle an issue.
-
-Issues on the issue tracker are categorized with the following labels:
-
-- **A**-prefixed labels state which area of the project an issue relates to.
-- **E**-prefixed labels show an estimate of the experience necessary to fix the issue.
-- **M**-prefixed labels are meta-issues regarding the management of the mdBook project itself
-- **S**-prefixed labels show the status of the issue
-- **C**-prefixed labels show the category of issue
-
-### Building mdBook
-
-mdBook builds on stable Rust, if you want to build mdBook from source, here are the steps to follow:
-
-1. Navigate to the directory of your choice
-0. Clone this repository with git.
-
-   ```
-   git clone https://github.com/rust-lang/mdBook.git
-   ```
-0. Navigate into the newly created `mdBook` directory
-0. Run `cargo build`
-
-The resulting binary can be found in `mdBook/target/debug/` under the name `mdbook` or `mdbook.exe`.
-
-### Code Quality
-
-We love code quality and Rust has some excellent tools to assist you with contributions.
-
-#### Formatting Code with rustfmt
-
-Before you make your Pull Request to the project, please run it through the `rustfmt` utility.
-This will ensure we have good quality source code that is better for us all to maintain.
-
-[rustfmt](https://github.com/rust-lang/rustfmt) has a lot more information on the project.
-The quick guide is
-
-1. Install it (`rustfmt` is usually installed by default via [rustup](https://rustup.rs/)):
-    ```
-    rustup component add rustfmt
-    ```
-1. You can now run `rustfmt` on a single file simply by...
-    ```
-    rustfmt src/path/to/your/file.rs
-    ```
-   ... or you can format the entire project with
-   ```
-   cargo fmt
-   ```
-   When run through `cargo` it will format all bin and lib files in the current package.
-
-For more information, such as running it from your favourite editor, please see the `rustfmt` project. [rustfmt](https://github.com/rust-lang/rustfmt)
-
-
-#### Finding Issues with Clippy
-
-[Clippy](https://doc.rust-lang.org/clippy/) is a code analyser/linter detecting mistakes, and therefore helps to improve your code.
-Like formatting your code with `rustfmt`, running clippy regularly and before your Pull Request will help us maintain awesome code.
-
-1. To install
-    ```
-    rustup component add clippy
-    ```
-2. Running clippy
-    ```
-    cargo clippy
-    ```
-
-### Change requirements
-
-Please consider the following when making a change:
-
-* Almost all changes that modify the Rust code must be accompanied with a test.
-
-* Almost all features and changes must update the documentation.
-  mdBook has the [mdBook Guide](https://rust-lang.github.io/mdBook/) whose source is at <https://github.com/rust-lang/mdBook/tree/master/guide>.
-
-* Almost all Rust items should be documented with doc comments.
-  See the [Rustdoc Book](https://doc.rust-lang.org/rustdoc/) for more information on writing doc comments.
-
-* Breaking the API can only be done in major SemVer releases.
-  These are done very infrequently, so it is preferred to avoid these when possible.
-  See [SemVer Compatibility](https://doc.rust-lang.org/cargo/reference/semver.html) for more information on what a SemVer breaking change is.
-
-  (Note: At this time, some SemVer breaking changes are inevitable due to the current code structure.
-  An example is adding new fields to the config structures.
-  These are intended to be fixed in the next major release.)
-
-* Similarly, the CLI interface is considered to be stable.
-  Care should be taken to avoid breaking existing workflows.
-
-* Check out the [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/) for guidelines on designing the API.
-
-### Making a pull-request
-
-When you feel comfortable that your changes could be integrated into mdBook, you can create a pull-request on GitHub.
-One of the core maintainers will then approve the changes or request some changes before it gets merged.
-
-That's it, happy contributions! :tada: :tada: :tada:
-
-## Browser compatibility and testing
-
-Currently we don't have a strict browser compatibility matrix due to our limited resources.
-We generally strive to keep mdBook compatible with a relatively recent browser on all of the most major platforms.
-That is, supporting Chrome, Safari, Firefox, Edge on Windows, macOS, Linux, iOS, and Android.
-If possible, do your best to avoid breaking older browser releases.
-
-Any change to the HTML or styling is encouraged to manually check on as many browsers and platforms that you can.
-Unfortunately at this time we don't have any automated UI or browser testing, so your assistance in testing is appreciated.
-
-## Updating highlight.js
-
-The following are instructions for updating [highlight.js](https://highlightjs.org/).
-
-1. Clone the repository at <https://github.com/highlightjs/highlight.js>
-1. Check out a tagged release (like `10.1.1`).
-1. Run `npm install`
-1. Run `node tools/build.js :common apache armasm coffeescript d handlebars haskell http julia nginx nim nix properties r scala x86asm yaml`
-1. Compare the language list that it spits out to the one in [`syntax-highlighting.md`](https://github.com/camelid/mdBook/blob/master/guide/src/format/theme/syntax-highlighting.md). If any are missing, add them to the list and rebuild (and update these docs). If any are added to the common set, add them to `syntax-highlighting.md`.
-1. Copy `build/highlight.min.js` to mdbook's directory [`highlight.js`](https://github.com/rust-lang/mdBook/blob/master/src/theme/highlight.js).
-1. Be sure to check the highlight.js [CHANGES](https://github.com/highlightjs/highlight.js/blob/main/CHANGES.md) for any breaking changes. Breaking changes that would affect users will need to wait until the next major release.
-1. Build mdbook with the new file and build some books with the new version and compare the output with a variety of languages to see if anything changes. The [test_book](https://github.com/rust-lang/mdBook/tree/master/test_book) contains a chapter with many languages to examine.
-
-## Publishing new releases
-
-Instructions for mdBook maintainers to publish a new release:
-
-1. Create a PR to update the version and update the CHANGELOG:
-    1. Update the version in `Cargo.toml`
-    2. Run `cargo test` to verify that everything is passing, and to update `Cargo.lock`.
-    3. Double-check for any SemVer breaking changes.
-       Try [`cargo-semver-checks`](https://crates.io/crates/cargo-semver-checks), though beware that the current version of mdBook isn't properly adhering to SemVer due to the lack of `#[non_exhaustive]` and other issues. See https://github.com/rust-lang/mdBook/issues/1835.
-    4. Update `CHANGELOG.md` with any changes that users may be interested in.
-    5. Update `continuous-integration.md` to update the version number for the installation instructions.
-    6. Commit the changes, and open a PR.
-2. After the PR has been merged, create a release in GitHub. This can either be done in the GitHub web UI, or on the command-line:
-   ```bash
-   MDBOOK_VERS="`cargo read-manifest | jq -r .version`" ; \
-    gh release create -R rust-lang/mdbook v$MDBOOK_VERS \
-        --title v$MDBOOK_VERS \
-        --notes "See https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-${MDBOOK_VERS//.} for a complete list of changes."
-   ```

-        Licensable by such Contributor to use, reproduce, make available,
-        modify, display, perform, distribute, and otherwise exploit its
-        Contributions, either on an unmodified basis, with Modifications, or

-
-     b. under Patent Claims of such Contributor to make, use, sell, offer for

-        Contributions or its Contributor Version.
-
-2.2. Effective Date
-
-     The licenses granted in Section 2.1 with respect to any Contribution
-     become effective for each Contribution on the date the Contributor first
-     distributes such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under
-     this License. No additional rights or licenses will be implied from the
-     distribution or licensing of Covered Software under this License.
-     Notwithstanding Section 2.1(b) above, no patent license is granted by a
-     Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party's
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of
-        its Contributions.
-
-     This License does not grant any rights in the trademarks, service marks,
-     or logos of any Contributor (except as may be necessary to comply with
-     the notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this
-     License (see Section 10.2) or under the terms of a Secondary License (if
-     permitted under the terms of Section 3.3).
-
-2.5. Representation
-
-     Each Contributor represents that the Contributor believes its
-     Contributions are its original creation(s) or it has sufficient rights to
-     grant the rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-     This License is not intended to limit any rights You have under
-     applicable copyright doctrines of fair use, fair dealing, or other
-     equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under
-     the terms of this License. You must inform recipients that the Source
-     Code Form of the Covered Software is governed by the terms of this
-     License, and how they can obtain a copy of this License. You may not
-     attempt to alter or restrict the recipients' rights in the Source Code
-     Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this
-        License, or sublicense it under different terms, provided that the
-        license for the Executable Form does not attempt to limit or alter the
-        recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for
-     the Covered Software. If the Larger Work is a combination of Covered
-     Software with a work governed by one or more Secondary Licenses, and the
-     Covered Software is not Incompatible With Secondary Licenses, this
-     License permits You to additionally distribute such Covered Software
-     under the terms of such Secondary License(s), so that the recipient of
-     the Larger Work may, at their option, further distribute the Covered
-     Software under the terms of either this License or such Secondary
-     License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices
-     (including copyright notices, patent notices, disclaimers of warranty, or
-     limitations of liability) contained within the Source Code Form of the
-     Covered Software, except that You may alter any license notices to the
-     extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on
-     behalf of any Contributor. You must make it absolutely clear that any
-     such warranty, support, indemnity, or liability obligation is offered by
-     You alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute,
-   judicial order, or regulation then You must: (a) comply with the terms of
-   this License to the maximum extent possible; and (b) describe the
-   limitations and the code they affect. Such description must be placed in a
-   text file included with all distributions of the Covered Software under
-   this License. Except to the extent prohibited by statute or regulation,
-   such description must be sufficiently detailed for a recipient of ordinary
-   skill to be able to understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing
-     basis, if such Contributor fails to notify You of the non-compliance by
-     some reasonable means prior to 60 days after You have come back into
-     compliance. Moreover, Your grants from a particular Contributor are
-     reinstated on an ongoing basis if such Contributor notifies You of the
-     non-compliance by some reasonable means, this is the first time You have
-     received notice of non-compliance with this License from such
-     Contributor, and You become compliant prior to 30 days after Your receipt
-     of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions,
-     counter-claims, and cross-claims) alleging that a Contributor Version
-     directly or indirectly infringes any patent, then the rights granted to
-     You by any and all Contributors for the Covered Software under Section
-     2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an "as is" basis,
-   without warranty of any kind, either expressed, implied, or statutory,
-   including, without limitation, warranties that the Covered Software is free
-   of defects, merchantable, fit for a particular purpose or non-infringing.
-   The entire risk as to the quality and performance of the Covered Software
-   is with You. Should any Covered Software prove defective in any respect,
-   You (not any Contributor) assume the cost of any necessary servicing,
-   repair, or correction. This disclaimer of warranty constitutes an essential
-   part of this License. No use of  any Covered Software is authorized under
-   this License except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from
-   such party's negligence to the extent applicable law prohibits such
-   limitation. Some jurisdictions do not allow the exclusion or limitation of
-   incidental or consequential damages, so this exclusion and limitation may
-   not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts
-   of a jurisdiction where the defendant maintains its principal place of
-   business and such litigation shall be governed by laws of that
-   jurisdiction, without reference to its conflict-of-law provisions. Nothing
-   in this Section shall prevent a party's ability to bring cross-claims or
-   counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject
-   matter hereof. If any provision of this License is held to be
-   unenforceable, such provision shall be reformed only to the extent
-   necessary to make it enforceable. Any law or regulation which provides that
-   the language of a contract shall be construed against the drafter shall not
-   be used to construe this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version
-      of the License under which You originally received the Covered Software,
-      or under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a
-      modified version of this License if you rename the license and remove
-      any references to the name of the license steward (except to note that
-      such modified license differs from this License).
-
-10.4. Distributing Source Code Form that is Incompatible With Secondary
-      Licenses If You choose to distribute Source Code Form that is
-      Incompatible With Secondary Licenses under the terms of this version of
-      the License, the notice described in Exhibit B of this License must be
-      attached.
-
-Exhibit A - Source Code Form License Notice

-      distributed with this file, You can
-      obtain one at
-      http://mozilla.org/MPL/2.0/.
-
-If it is not possible or desirable to put the notice in a particular file,
-then You may include the notice in a location (such as a LICENSE file in a
-relevant directory) where a recipient would be likely to look for such a
-notice.
-
-You may add additional accurate notices of copyright ownership.
-
-Exhibit B - "Incompatible With Secondary Licenses" Notice
-
-      This Source Code Form is "Incompatible
-      With Secondary Licenses", as defined by

+<p>The build command is used to render your book:</p>
+<pre><code class="language-bash">mdbook build
+</code></pre>
+<p>It will try to parse your <code>SUMMARY.md</code> file to understand the structure of your
+book and fetch the corresponding files. Note that this will also create files
+mentioned in <code>SUMMARY.md</code> which are not yet present.</p>
+<p>The rendered output will maintain the same directory structure as the source for
+convenience. Large books will therefore remain structured when rendered.</p>
+<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
+<p>The <code>build</code> command can take a directory as an argument to use as the book's
+root instead of the current working directory.</p>
+<pre><code class="language-bash">mdbook build path/to/book
+</code></pre>
+<h4 id="--open"><a class="header" href="#--open">--open</a></h4>
+<p>When you use the <code>--open</code> (<code>-o</code>) flag, mdbook will open the rendered book in
+your default web browser after building it.</p>
+<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
+<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
+book. Relative paths are interpreted relative to the book's root directory. If
+not specified it will default to the value of the <code>build.build-dir</code> key in
+<code>book.toml</code>, or to <code>./book</code>.</p>
+<hr />
+<p><em><strong>Note:</strong></em> <em>The build command copies all files (excluding files with <code>.md</code> extension) from the source directory
+into the build directory.</em></p>

+<p>The completions command is used to generate auto-completions for some common shells.
+This means when you type <code>mdbook</code> in your shell, you can then press your shell's auto-complete key (usually the Tab key) and it may display what the valid options are, or finish partial input.</p>
+<p>The completions first need to be installed for your shell:</p>
+<pre><code class="language-bash"># bash
+mdbook completions bash &gt; ~/.local/share/bash-completion/completions/mdbook
+# oh-my-zsh
+mdbook completions zsh &gt; ~/.oh-my-zsh/completions/_mdbook
+autoload -U compinit &amp;&amp; compinit
+</code></pre>
+<p>The command prints a completion script for the given shell.
+Run <code>mdbook completions --help</code> for a list of supported shells.</p>
+<p>Where to place the completions depend on which shell you are using and your operating system.
+Consult your shell's documentation for more information one where to place the script.</p>

+<p>There is some minimal boilerplate that is the same for every new book. It's for
+this purpose that mdBook includes an <code>init</code> command.</p>
+<p>The <code>init</code> command is used like this:</p>
+<pre><code class="language-bash">mdbook init
+</code></pre>
+<p>When using the <code>init</code> command for the first time, a couple of files will be set
+up for you:</p>
+<pre><code class="language-bash">book-test/
+├── book
+└── src
+    ├── chapter_1.md
+    └── SUMMARY.md
+</code></pre>
+<ul>
+<li>
+<p>The <code>src</code> directory is where you write your book in markdown. It contains all
+the source files, configuration files, etc.</p>
+</li>
+<li>
+<p>The <code>book</code> directory is where your book is rendered. All the output is ready
+to be uploaded to a server to be seen by your audience.</p>
+</li>
+<li>
+<p>The <code>SUMMARY.md</code> is the skeleton of your
+book, and is discussed in more detail <a href="../format/summary.html">in another
+chapter</a>.</p>
+</li>
+</ul>
+<h4 id="tip-generate-chapters-from-summarymd"><a class="header" href="#tip-generate-chapters-from-summarymd">Tip: Generate chapters from SUMMARY.md</a></h4>
+<p>When a <code>SUMMARY.md</code> file already exists, the <code>init</code> command will first parse it
+and generate the missing files according to the paths used in the <code>SUMMARY.md</code>.
+This allows you to think and create the whole structure of your book and then
+let mdBook generate it for you.</p>
+<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
+<p>The <code>init</code> command can take a directory as an argument to use as the book's root
+instead of the current working directory.</p>
+<pre><code class="language-bash">mdbook init path/to/book
+</code></pre>
+<h4 id="--theme"><a class="header" href="#--theme">--theme</a></h4>
+<p>When you use the <code>--theme</code> flag, the default theme will be copied into a
+directory called <code>theme</code> in your source directory so that you can modify it.</p>
+<p>The theme is selectively overwritten, this means that if you don't want to
+overwrite a specific file, just delete it and the default file will be used.</p>
+<h4 id="--title"><a class="header" href="#--title">--title</a></h4>
+<p>Specify a title for the book. If not supplied, an interactive prompt will ask for
+a title.</p>
+<pre><code class="language-bash">mdbook init --title="my amazing book"
+</code></pre>
+<h4 id="--ignore"><a class="header" href="#--ignore">--ignore</a></h4>
+<p>Create a <code>.gitignore</code> file configured to ignore the <code>book</code> directory created when <a href="build.html">building</a> a book.
+If not supplied, an interactive prompt will ask whether it should be created.</p>
+<pre><code class="language-bash">mdbook init --ignore=none
+</code></pre>
+<pre><code class="language-bash">mdbook init --ignore=git
+</code></pre>
+<h4 id="--force"><a class="header" href="#--force">--force</a></h4>
+<p>Skip the prompts to create a <code>.gitignore</code> and for the title for the book.</p>

+<p>The serve command is used to preview a book by serving it via HTTP at
+<code>localhost:3000</code> by default:</p>
+<pre><code class="language-bash">mdbook serve
+</code></pre>
+<p>The <code>serve</code> command  watches the book's <code>src</code> directory for
+changes, rebuilding the book and refreshing clients for each change; this includes
+re-creating deleted files still mentioned in <code>SUMMARY.md</code>! A websocket
+connection is used to trigger the client-side refresh.</p>
+<p><em><strong>Note:</strong></em> <em>The <code>serve</code> command is for testing a book's HTML output, and is not
+intended to be a complete HTTP server for a website.</em></p>
+<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
+<p>The <code>serve</code> command can take a directory as an argument to use as the book's
+root instead of the current working directory.</p>
+<pre><code class="language-bash">mdbook serve path/to/book
+</code></pre>
+<h3 id="server-options"><a class="header" href="#server-options">Server options</a></h3>
+<p>The <code>serve</code> hostname defaults to <code>localhost</code>, and the port defaults to <code>3000</code>. Either option can be specified on the command line:</p>
+<pre><code class="language-bash">mdbook serve path/to/book -p 8000 -n 127.0.0.1 
+</code></pre>
+<h4 id="--open"><a class="header" href="#--open">--open</a></h4>
+<p>When you use the <code>--open</code> (<code>-o</code>) flag, mdbook will open the book in your
+default web browser after starting the server.</p>
+<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
+<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
+book. Relative paths are interpreted relative to the book's root directory. If
+not specified it will default to the value of the <code>build.build-dir</code> key in
+<code>book.toml</code>, or to <code>./book</code>.</p>
+<h4 id="specify-exclude-patterns"><a class="header" href="#specify-exclude-patterns">Specify exclude patterns</a></h4>
+<p>The <code>serve</code> command will not automatically trigger a build for files listed in
+the <code>.gitignore</code> file in the book root directory. The <code>.gitignore</code> file may
+contain file patterns described in the <a href="https://git-scm.com/docs/gitignore">gitignore
+documentation</a>. This can be useful for
+ignoring temporary files created by some editors.</p>
+<p><em><strong>Note:</strong></em> <em>Only the <code>.gitignore</code> from the book root directory is used. Global
+<code>$HOME/.gitignore</code> or <code>.gitignore</code> files in parent directories are not used.</em></p>

+<p>When writing a book, you sometimes need to automate some tests. For example,
+<a href="https://doc.rust-lang.org/stable/book/">The Rust Programming Book</a> uses a lot
+of code examples that could get outdated. Therefore it is very important for
+them to be able to automatically test these code examples.</p>
+<p>mdBook supports a <code>test</code> command that will run all available tests in a book. At
+the moment, only Rust tests are supported.</p>
+<h4 id="disable-tests-on-a-code-block"><a class="header" href="#disable-tests-on-a-code-block">Disable tests on a code block</a></h4>
+<p>rustdoc doesn't test code blocks which contain the <code>ignore</code> attribute:</p>
+<pre><code>```rust,ignore
+fn main() {}
+```
+</code></pre>
+<p>rustdoc also doesn't test code blocks which specify a language other than Rust:</p>
+<pre><code>```markdown
+**Foo**: _bar_
+```
+</code></pre>
+<p>rustdoc <em>does</em> test code blocks which have no language specified:</p>
+<pre><code>```
+This is going to cause an error!
+```
+</code></pre>
+<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
+<p>The <code>test</code> command can take a directory as an argument to use as the book's root
+instead of the current working directory.</p>
+<pre><code class="language-bash">mdbook test path/to/book
+</code></pre>
+<h4 id="--library-path"><a class="header" href="#--library-path">--library-path</a></h4>
+<p>The <code>--library-path</code> (<code>-L</code>) option allows you to add directories to the library
+search path used by <code>rustdoc</code> when it builds and tests the examples. Multiple
+directories can be specified with multiple options (<code>-L foo -L bar</code>) or with a
+comma-delimited list (<code>-L foo,bar</code>). The path should point to the Cargo
+<a href="https://doc.rust-lang.org/cargo/guide/build-cache.html">build cache</a> <code>deps</code> directory that
+contains the build output of your project. For example, if your Rust project's book is in a directory
+named <code>my-book</code>, the following command would include the crate's dependencies when running <code>test</code>:</p>
+<pre><code class="language-shell">mdbook test my-book -L target/debug/deps/
+</code></pre>
+<p>See the <code>rustdoc</code> command-line <a href="https://doc.rust-lang.org/rustdoc/command-line-arguments.html#-l--library-path-where-to-look-for-dependencies">documentation</a>
+for more information.</p>
+<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
+<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
+book. Relative paths are interpreted relative to the book's root directory. If
+not specified it will default to the value of the <code>build.build-dir</code> key in
+<code>book.toml</code>, or to <code>./book</code>.</p>
+<h4 id="--chapter"><a class="header" href="#--chapter">--chapter</a></h4>
+<p>The <code>--chapter</code> (<code>-c</code>) option allows you to test a specific chapter of the
+book using the chapter name or the relative path to the chapter.</p>

+<p>The <code>watch</code> command is useful when you want your book to be rendered on every
+file change. You could repeatedly issue <code>mdbook build</code> every time a file is
+changed. But using <code>mdbook watch</code> once will watch your files and will trigger a
+build automatically whenever you modify a file; this includes re-creating
+deleted files still mentioned in <code>SUMMARY.md</code>!</p>
+<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
+<p>The <code>watch</code> command can take a directory as an argument to use as the book's
+root instead of the current working directory.</p>
+<pre><code class="language-bash">mdbook watch path/to/book
+</code></pre>
+<h4 id="--open"><a class="header" href="#--open">--open</a></h4>
+<p>When you use the <code>--open</code> (<code>-o</code>) option, mdbook will open the rendered book in
+your default web browser.</p>
+<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
+<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
+book. Relative paths are interpreted relative to the book's root directory. If
+not specified it will default to the value of the <code>build.build-dir</code> key in
+<code>book.toml</code>, or to <code>./book</code>.</p>
+<h4 id="specify-exclude-patterns"><a class="header" href="#specify-exclude-patterns">Specify exclude patterns</a></h4>
+<p>The <code>watch</code> command will not automatically trigger a build for files listed in
+the <code>.gitignore</code> file in the book root directory. The <code>.gitignore</code> file may
+contain file patterns described in the <a href="https://git-scm.com/docs/gitignore">gitignore
+documentation</a>. This can be useful for
+ignoring temporary files created by some editors.</p>
+<p><em>Note: Only <code>.gitignore</code> from book root directory is used. Global
+<code>$HOME/.gitignore</code> or <code>.gitignore</code> files in parent directories are not used.</em></p>

+<p>There are a variety of services such as <a href="https://docs.github.com/en/actions">GitHub Actions</a> or <a href="https://docs.gitlab.com/ee/ci/">GitLab CI/CD</a> which can be used to test and deploy your book automatically.</p>
+<p>The following provides some general guidelines on how to configure your service to run mdBook.
+Specific recipes can be found at the <a href="https://github.com/rust-lang/mdBook/wiki/Automated-Deployment">Automated Deployment</a> wiki page.</p>
+<h2 id="installing-mdbook"><a class="header" href="#installing-mdbook">Installing mdBook</a></h2>
+<p>There are several different strategies for installing mdBook.
+The particular method depends on your needs and preferences.</p>
+<h3 id="pre-compiled-binaries"><a class="header" href="#pre-compiled-binaries">Pre-compiled binaries</a></h3>
+<p>Perhaps the easiest method is to use the pre-compiled binaries found on the <a href="https://github.com/rust-lang/mdBook/releases">GitHub Releases page</a>.
+A simple approach would be to use the popular <code>curl</code> CLI tool to download the executable:</p>
+<pre><code class="language-sh">mkdir bin
+curl -sSL https://github.com/rust-lang/mdBook/releases/download/v0.4.37/mdbook-v0.4.37-x86_64-unknown-linux-gnu.tar.gz | tar -xz --directory=bin
+bin/mdbook build
+</code></pre>
+<p>Some considerations for this approach:</p>
+<ul>
+<li>This is relatively fast, and does not necessarily require dealing with caching.</li>
+<li>This does not require installing Rust.</li>
+<li>Specifying a specific URL means you have to manually update your script to get a new version.
+This may be a benefit if you want to lock to a specific version.
+However, some users prefer to automatically get a newer version when they are published.</li>
+<li>You are reliant on the GitHub CDN being available.</li>
+</ul>
+<h3 id="building-from-source"><a class="header" href="#building-from-source">Building from source</a></h3>
+<p>Building from source will require having Rust installed.
+Some services have Rust pre-installed, but if your service does not, you will need to add a step to install it.</p>
+<p>After Rust is installed, <code>cargo install</code> can be used to build and install mdBook.
+We recommend using a SemVer version specifier so that you get the latest <strong>non-breaking</strong> version of mdBook.
+For example:</p>
+<pre><code class="language-sh">cargo install mdbook --no-default-features --features search --vers "^0.4" --locked
+</code></pre>
+<p>This includes several recommended options:</p>
+<ul>
+<li><code>--no-default-features</code> — Disables features like the HTTP server used by <code>mdbook serve</code> that is likely not needed on CI.
+This will speed up the build time significantly.</li>
+<li><code>--features search</code> — Disabling default features means you should then manually enable features that you want, such as the built-in <a href="guide/reading.html#search">search</a> capability.</li>
+<li><code>--vers "^0.4"</code> — This will install the most recent version of the <code>0.4</code> series.
+However, versions after like <code>0.5.0</code> won't be installed, as they may break your build.
+Cargo will automatically upgrade mdBook if you have an older version already installed.</li>
+<li><code>--locked</code> — This will use the dependencies that were used when mdBook was released.
+Without <code>--locked</code>, it will use the latest version of all dependencies, which may include some fixes since the last release, but may also (rarely) cause build problems.</li>
+</ul>
+<p>You will likely want to investigate caching options, as building mdBook can be somewhat slow.</p>
+<h2 id="running-tests"><a class="header" href="#running-tests">Running tests</a></h2>
+<p>You may want to run tests using <a href="cli/test.html"><code>mdbook test</code></a> every time you push a change or create a pull request.
+This can be used to validate Rust code examples in the book.</p>
+<p>This will require having Rust installed.
+Some services have Rust pre-installed, but if your service does not, you will need to add a step to install it.</p>
+<p>Other than making sure the appropriate version of Rust is installed, there's not much more than just running <code>mdbook test</code> from the book directory.</p>
+<p>You may also want to consider running other kinds of tests, like <a href="https://github.com/Michael-F-Bryan/mdbook-linkcheck#continuous-integration">mdbook-linkcheck</a> which will check for broken links.
+Or if you have your own style checks, spell checker, or any other tests it might be good to run them in CI.</p>
+<h2 id="deploying"><a class="header" href="#deploying">Deploying</a></h2>
+<p>You may want to automatically deploy your book.
+Some may want to do this every time a change is pushed, and others may want to only deploy when a specific release is tagged.</p>
+<p>You'll also need to understand the specifics on how to push a change to your web service.
+For example, <a href="https://docs.github.com/en/pages">GitHub Pages</a> just requires committing the output onto a specific git branch.
+Other services may require using something like SSH to connect to a remote server.</p>
+<p>The basic outline is that you need to run <code>mdbook build</code> to generate the output, and then transfer the files (which are in the <code>book</code> directory) to the correct location.</p>
+<p>You may then want to consider if you need to invalidate any caches on your web service.</p>
+<p>See the <a href="https://github.com/rust-lang/mdBook/wiki/Automated-Deployment">Automated Deployment</a> wiki page for examples of various different services.</p>
+<h3 id="404-handling"><a class="header" href="#404-handling">404 handling</a></h3>
+<p>mdBook automatically generates a 404 page to be used for broken links.
+The default output is a file named <code>404.html</code> at the root of the book.
+Some services like <a href="https://docs.github.com/en/pages">GitHub Pages</a> will automatically use this page for broken links.
+For other services, you may want to consider configuring the web server to use this page as it will provide the reader navigation to get back to the book.</p>
+<p>If your book is not deployed at the root of the domain, then you should set the <a href="format/configuration/renderers.html#html-renderer-options"><code>output.html.site-url</code></a> setting so that the 404 page works correctly.
+It needs to know where the book is deployed in order to load the static files (like CSS) correctly.
+For example, this guide is deployed at <a href="https://rust-lang.github.io/mdBook/">https://rust-lang.github.io/mdBook/</a>, and the <code>site-url</code> setting is configured like this:</p>
+<pre><code class="language-toml"># book.toml
+[output.html]
+site-url = "/mdBook/"
+</code></pre>
+<p>You can customize the look of the 404 page by creating a file named <code>src/404.md</code> in your book.
+If you want to use a different filename, you can set <a href="format/configuration/renderers.html#html-renderer-options"><code>output.html.input-404</code></a> to a different filename.</p>

+<p>A "backend" is simply a program which <code>mdbook</code> will invoke during the book
+rendering process. This program is passed a JSON representation of the book and
+configuration information via <code>stdin</code>. Once the backend receives this
+information it is free to do whatever it wants.</p>
+<p>See <a href="../format/configuration/renderers.html">Configuring Renderers</a> for more information about using backends.</p>
+<p>The community has developed several backends.
+See the <a href="https://github.com/rust-lang/mdBook/wiki/Third-party-plugins">Third Party Plugins</a> wiki page for a list of available backends.</p>
+<h2 id="setting-up"><a class="header" href="#setting-up">Setting Up</a></h2>
+<p>This page will step you through creating your own alternative backend in the form
+of a simple word counting program. Although it will be written in Rust, there's
+no reason why it couldn't be accomplished using something like Python or Ruby.</p>
+<p>First you'll want to create a new binary program and add <code>mdbook</code> as a
+dependency.</p>
+<pre><code class="language-shell">$ cargo new --bin mdbook-wordcount
+$ cd mdbook-wordcount
+$ cargo add mdbook
+</code></pre>
+<p>When our <code>mdbook-wordcount</code> plugin is invoked, <code>mdbook</code> will send it a JSON
+version of <a href="https://docs.rs/mdbook/*/mdbook/renderer/struct.RenderContext.html"><code>RenderContext</code></a> via our plugin's <code>stdin</code>. For convenience, there's
+a <a href="https://docs.rs/mdbook/*/mdbook/renderer/struct.RenderContext.html#method.from_json"><code>RenderContext::from_json()</code></a> constructor which will load a <code>RenderContext</code>.</p>
+<p>This is all the boilerplate necessary for our backend to load the book.</p>
+<pre><pre class="playground"><code class="language-rust edition2018">// src/main.rs
+extern crate mdbook;
+
+use std::io;
+use mdbook::renderer::RenderContext;
+
+fn main() {
+    let mut stdin = io::stdin();
+    let ctx = RenderContext::from_json(&amp;mut stdin).unwrap();
+}</code></pre></pre>
+<blockquote>
+<p><strong>Note:</strong> The <code>RenderContext</code> contains a <code>version</code> field. This lets backends
+figure out whether they are compatible with the version of <code>mdbook</code> it's being
+called by. This <code>version</code> comes directly from the corresponding field in
+<code>mdbook</code>'s <code>Cargo.toml</code>.</p>
+</blockquote>
+<p>It is recommended that backends use the <a href="https://crates.io/crates/semver"><code>semver</code></a> crate to inspect this field
+and emit a warning if there may be a compatibility issue.</p>
+<h2 id="inspecting-the-book"><a class="header" href="#inspecting-the-book">Inspecting the Book</a></h2>
+<p>Now our backend has a copy of the book, lets count how many words are in each
+chapter!</p>
+<p>Because the <code>RenderContext</code> contains a <a href="https://docs.rs/mdbook/*/mdbook/book/struct.Book.html"><code>Book</code></a> field (<code>book</code>), and a <code>Book</code> has
+the <a href="https://docs.rs/mdbook/*/mdbook/book/struct.Book.html#method.iter"><code>Book::iter()</code></a> method for iterating over all items in a <code>Book</code>, this step
+turns out to be just as easy as the first.</p>
+<pre><pre class="playground"><code class="language-rust edition2018">
+fn main() {
+    let mut stdin = io::stdin();
+    let ctx = RenderContext::from_json(&amp;mut stdin).unwrap();
+
+    for item in ctx.book.iter() {
+        if let BookItem::Chapter(ref ch) = *item {
+            let num_words = count_words(ch);
+            println!("{}: {}", ch.name, num_words);
+        }
+    }
+}
+
+fn count_words(ch: &amp;Chapter) -&gt; usize {
+    ch.content.split_whitespace().count()
+}</code></pre></pre>
+<h2 id="enabling-the-backend"><a class="header" href="#enabling-the-backend">Enabling the Backend</a></h2>
+<p>Now we've got the basics running, we want to actually use it. First, install the
+program.</p>
+<pre><code class="language-shell">$ cargo install --path .
+</code></pre>
+<p>Then <code>cd</code> to the particular book you'd like to count the words of and update its
+<code>book.toml</code> file.</p>
+<pre><code class="language-diff">  [book]
+  title = "mdBook Documentation"
+  description = "Create book from markdown files. Like Gitbook but implemented in Rust"
+  authors = ["Mathieu David", "Michael-F-Bryan"]
+
++ [output.html]
+
++ [output.wordcount]
+</code></pre>
+<p>When it loads a book into memory, <code>mdbook</code> will inspect your <code>book.toml</code> file to
+try and figure out which backends to use by looking for all <code>output.*</code> tables.
+If none are provided it'll fall back to using the default HTML renderer.</p>
+<p>Notably, this means if you want to add your own custom backend you'll also need
+to make sure to add the HTML backend, even if its table just stays empty.</p>
+<p>Now you just need to build your book like normal, and everything should <em>Just
+Work</em>.</p>

+</code></pre>
+<p>The reason we didn't need to specify the full name/path of our <code>wordcount</code>
+backend is because <code>mdbook</code> will try to <em>infer</em> the program's name via
+convention. The executable for the <code>foo</code> backend is typically called
+<code>mdbook-foo</code>, with an associated <code>[output.foo]</code> entry in the <code>book.toml</code>. To
+explicitly tell <code>mdbook</code> what command to invoke (it may require command-line
+arguments or be an interpreted script), you can use the <code>command</code> field.</p>
+<pre><code class="language-diff">  [book]
+  title = "mdBook Documentation"
+  description = "Create book from markdown files. Like Gitbook but implemented in Rust"
+  authors = ["Mathieu David", "Michael-F-Bryan"]

+  [output.wordcount]
++ command = "python /path/to/wordcount.py"
+</code></pre>
+<h2 id="configuration"><a class="header" href="#configuration">Configuration</a></h2>
+<p>Now imagine you don't want to count the number of words on a particular chapter
+(it might be generated text/code, etc). The canonical way to do this is via the
+usual <code>book.toml</code> configuration file by adding items to your <code>[output.foo]</code>
+table.</p>
+<p>The <code>Config</code> can be treated roughly as a nested hashmap which lets you call
+methods like <code>get()</code> to access the config's contents, with a
+<code>get_deserialized()</code> convenience method for retrieving a value and automatically
+deserializing to some arbitrary type <code>T</code>.</p>
+<p>To implement this, we'll create our own serializable <code>WordcountConfig</code> struct
+which will encapsulate all configuration for this backend.</p>
+<p>First add <code>serde</code> and <code>serde_derive</code> to your <code>Cargo.toml</code>,</p>
+<pre><code>$ cargo add serde serde_derive
+</code></pre>
+<p>And then you can create the config struct,</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">#![allow(unused)]
+</span><span class="boring">fn main() {
+</span>extern crate serde;
+#[macro_use]

+#[serde(default, rename_all = "kebab-case")]
+pub struct WordcountConfig {
+  pub ignores: Vec&lt;String&gt;,
+}
+<span class="boring">}</span></code></pre></pre>
+<p>Now we just need to deserialize the <code>WordcountConfig</code> from our <code>RenderContext</code>
+and then add a check to make sure we skip ignored chapters.</p>
+<pre><code class="language-diff">  fn main() {
+      let mut stdin = io::stdin();
+      let ctx = RenderContext::from_json(&amp;mut stdin).unwrap();
++     let cfg: WordcountConfig = ctx.config
++         .get_deserialized("output.wordcount")
++         .unwrap_or_default();
+
+      for item in ctx.book.iter() {
+          if let BookItem::Chapter(ref ch) = *item {
++             if cfg.ignores.contains(&amp;ch.name) {
++                 continue;
++             }
++
+              let num_words = count_words(ch);
+              println!("{}: {}", ch.name, num_words);

+      }
+  }
+</code></pre>
+<h2 id="output-and-signalling-failure"><a class="header" href="#output-and-signalling-failure">Output and Signalling Failure</a></h2>
+<p>While it's nice to print word counts to the terminal when a book is built, it
+might also be a good idea to output them to a file somewhere. <code>mdbook</code> tells a
+backend where it should place any generated output via the <code>destination</code> field
+in <a href="https://docs.rs/mdbook/*/mdbook/renderer/struct.RenderContext.html"><code>RenderContext</code></a>.</p>
+<pre><code class="language-diff">+ use std::fs::{self, File};

+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> There is no guarantee that the destination directory exists or is
+empty (<code>mdbook</code> may leave the previous contents to let backends do caching),
+so it's always a good idea to create it with <code>fs::create_dir_all()</code>.</p>
+<p>If the destination directory already exists, don't assume it will be empty.
+To allow backends to cache the results from previous runs, <code>mdbook</code> may leave
+old content in the directory.</p>
+</blockquote>
+<p>There's always the possibility that an error will occur while processing a book
+(just look at all the <code>unwrap()</code>'s we've written already), so <code>mdbook</code> will
+interpret a non-zero exit code as a rendering failure.</p>
+<p>For example, if we wanted to make sure all chapters have an <em>even</em> number of
+words, erroring out if an odd number is encountered, then you may do something
+like this:</p>
+<pre><code class="language-diff">+ use std::process;

+
++             if cfg.deny_odds &amp;&amp; num_words % 2 == 1 {
++               eprintln!("{} has an odd number of words!", ch.name);
++               process::exit(1);

+  pub struct WordcountConfig {
+      pub ignores: Vec&lt;String&gt;,

+<p>While <code>mdbook</code> is mainly used as a command line tool, you can also import the
+underlying library directly and use that to manage a book. It also has a fairly
+flexible plugin mechanism, allowing you to create your own custom tooling and
+consumers (often referred to as <em>backends</em>) if you need to do some analysis of
+the book or render it in a different format.</p>
+<p>The <em>For Developers</em> chapters are here to show you the more advanced usage of
+<code>mdbook</code>.</p>
+<p>The two main ways a developer can hook into the book's build process is via,</p>
+<ul>
+<li><a href="preprocessors.html">Preprocessors</a></li>
+<li><a href="backends.html">Alternative Backends</a></li>
+</ul>
+<h2 id="the-build-process"><a class="header" href="#the-build-process">The Build Process</a></h2>
+<p>The process of rendering a book project goes through several steps.</p>
+<ol>
+<li>Load the book
+<ul>
+<li>Parse the <code>book.toml</code>, falling back to the default <code>Config</code> if it doesn't
+exist</li>
+<li>Load the book chapters into memory</li>
+<li>Discover which preprocessors/backends should be used</li>
+</ul>
+</li>
+<li>For each backend:
+<ol>
+<li>Run all the preprocessors.</li>
+<li>Call the backend to render the processed result.</li>
+</ol>
+</li>
+</ol>
+<h2 id="using-mdbook-as-a-library"><a class="header" href="#using-mdbook-as-a-library">Using <code>mdbook</code> as a Library</a></h2>
+<p>The <code>mdbook</code> binary is just a wrapper around the <code>mdbook</code> crate, exposing its
+functionality as a command-line program. As such it is quite easy to create your
+own programs which use <code>mdbook</code> internally, adding your own functionality (e.g.
+a custom preprocessor) or tweaking the build process.</p>
+<p>The easiest way to find out how to use the <code>mdbook</code> crate is by looking at the
+<a href="https://docs.rs/mdbook/*/mdbook/">API Docs</a>. The top level documentation explains how one would use the
+<a href="https://docs.rs/mdbook/*/mdbook/book/struct.MDBook.html"><code>MDBook</code></a> type to load and build a book, while the <a href="https://docs.rs/mdbook/*/mdbook/config/index.html">config</a> module gives a good
+explanation on the configuration system.</p>

+<p>A <em>preprocessor</em> is simply a bit of code which gets run immediately after the
+book is loaded and before it gets rendered, allowing you to update and mutate
+the book. Possible use cases are:</p>
+<ul>
+<li>Creating custom helpers like <code>{{#include /path/to/file.md}}</code></li>
+<li>Substituting in latex-style expressions (<code>$$ \frac{1}{3} $$</code>) with their
+mathjax equivalents</li>
+</ul>
+<p>See <a href="../format/configuration/preprocessors.html">Configuring Preprocessors</a> for more information about using preprocessors.</p>
+<h2 id="hooking-into-mdbook"><a class="header" href="#hooking-into-mdbook">Hooking Into MDBook</a></h2>
+<p>MDBook uses a fairly simple mechanism for discovering third party plugins.
+A new table is added to <code>book.toml</code> (e.g. <code>[preprocessor.foo]</code> for the <code>foo</code>
+preprocessor) and then <code>mdbook</code> will try to invoke the <code>mdbook-foo</code> program as
+part of the build process.</p>
+<p>Once the preprocessor has been defined and the build process starts, mdBook executes the command defined in the <code>preprocessor.foo.command</code> key twice.
+The first time it runs the preprocessor to determine if it supports the given renderer.
+mdBook passes two arguments to the process: the first argument is the string <code>supports</code> and the second argument is the renderer name.
+The preprocessor should exit with a status code 0 if it supports the given renderer, or return a non-zero exit code if it does not.</p>
+<p>If the preprocessor supports the renderer, then mdbook runs it a second time, passing JSON data into stdin.
+The JSON consists of an array of <code>[context, book]</code> where <code>context</code> is the serialized object <a href="https://docs.rs/mdbook/latest/mdbook/preprocess/struct.PreprocessorContext.html"><code>PreprocessorContext</code></a> and <code>book</code> is a <a href="https://docs.rs/mdbook/latest/mdbook/book/struct.Book.html"><code>Book</code></a> object containing the content of the book.</p>
+<p>The preprocessor should return the JSON format of the <a href="https://docs.rs/mdbook/latest/mdbook/book/struct.Book.html"><code>Book</code></a> object to stdout, with any modifications it wishes to perform.</p>
+<p>The easiest way to get started is by creating your own implementation of the
+<code>Preprocessor</code> trait (e.g. in <code>lib.rs</code>) and then creating a shell binary which
+translates inputs to the correct <code>Preprocessor</code> method. For convenience, there
+is <a href="https://github.com/rust-lang/mdBook/blob/master/examples/nop-preprocessor.rs">an example no-op preprocessor</a> in the <code>examples/</code> directory which can easily
+be adapted for other preprocessors.</p>

+<a href="https://docs.rs/mdbook/latest/mdbook/preprocess/trait.Preprocessor.html#method.parse_input"><code>CmdPreprocessor::parse_input()</code></a> function to deserialize the JSON written to
+<code>stdin</code>. Then each chapter of the <code>Book</code> can be mutated in-place via
+<a href="https://docs.rs/mdbook/latest/mdbook/book/struct.Book.html#method.for_each_mut"><code>Book::for_each_mut()</code></a>, and then written to <code>stdout</code> with the <code>serde_json</code>
+crate.</p>
+<p>Chapters can be accessed either directly (by recursively iterating over
+chapters) or via the <code>Book::for_each_mut()</code> convenience method.</p>
+<p>The <code>chapter.content</code> is just a string which happens to be markdown. While it's
+entirely possible to use regular expressions or do a manual find &amp; replace,
+you'll probably want to process the input into something more computer-friendly.
+The <a href="https://crates.io/crates/pulldown-cmark"><code>pulldown-cmark</code></a> crate implements a production-quality event-based
+Markdown parser, with the <a href="https://crates.io/crates/pulldown-cmark-to-cmark"><code>pulldown-cmark-to-cmark</code></a> crate allowing you to
+translate events back into markdown text.</p>
+<p>The following code block shows how to remove all emphasis from markdown,
+without accidentally breaking the document.</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">#![allow(unused)]
+</span><span class="boring">fn main() {
+</span>fn remove_emphasis(
+    num_removed_items: &amp;mut usize,
+    chapter: &amp;mut Chapter,
+) -&gt; Result&lt;String&gt; {
+    let mut buf = String::with_capacity(chapter.content.len());
+
+    let events = Parser::new(&amp;chapter.content).filter(|e| {
+        let should_keep = match *e {
+            Event::Start(Tag::Emphasis)
+            | Event::Start(Tag::Strong)
+            | Event::End(Tag::Emphasis)
+            | Event::End(Tag::Strong) =&gt; false,
+            _ =&gt; true,
+        };
+        if !should_keep {
+            *num_removed_items += 1;
+        }
+        should_keep
+    });
+
+    cmark(events, &amp;mut buf, None).map(|_| buf).map_err(|err| {
+        Error::from(format!("Markdown serialization failed: {}", err))
+    })
+}
+<span class="boring">}</span></code></pre></pre>

+<p>The fact that mdBook utilizes stdin and stdout to communicate with the preprocessors makes it easy to implement them in a language other than Rust.
+The following code shows how to implement a simple preprocessor in Python, which will modify the content of the first chapter.
+The example below follows the configuration shown above with <code>preprocessor.foo.command</code> actually pointing to a Python script.</p>
+<pre><code class="language-python">import json
+import sys
+
+
+if __name__ == '__main__':
+    if len(sys.argv) &gt; 1: # we check if we received any argument
+        if sys.argv[1] == "supports": 
+            # then we are good to return an exit status code of 0, since the other argument will just be the renderer's name
+            sys.exit(0)
+
+    # load both the context and the book representations from stdin
+    context, book = json.load(sys.stdin)
+    # and now, we can just modify the content of the first chapter
+    book['sections'][0]['Chapter']['content'] = '# Hello'
+    # we are done with the book's modification, we can just print it to stdout, 
+    print(json.dumps(book))

+<p>All configuration values can be overridden from the command line by setting the
+corresponding environment variable. Because many operating systems restrict
+environment variables to be alphanumeric characters or <code>_</code>, the configuration
+key needs to be formatted slightly differently to the normal <code>foo.bar.baz</code> form.</p>
+<p>Variables starting with <code>MDBOOK_</code> are used for configuration. The key is created
+by removing the <code>MDBOOK_</code> prefix and turning the resulting string into
+<code>kebab-case</code>. Double underscores (<code>__</code>) separate nested keys, while a single
+underscore (<code>_</code>) is replaced with a dash (<code>-</code>).</p>
+<p>For example:</p>
+<ul>
+<li><code>MDBOOK_foo</code> -&gt; <code>foo</code></li>
+<li><code>MDBOOK_FOO</code> -&gt; <code>foo</code></li>
+<li><code>MDBOOK_FOO__BAR</code> -&gt; <code>foo.bar</code></li>
+<li><code>MDBOOK_FOO_BAR</code> -&gt; <code>foo-bar</code></li>
+<li><code>MDBOOK_FOO_bar__baz</code> -&gt; <code>foo-bar.baz</code></li>
+</ul>
+<p>So by setting the <code>MDBOOK_BOOK__TITLE</code> environment variable you can override the
+book's title without needing to touch your <code>book.toml</code>.</p>
+<blockquote>
+<p><strong>Note:</strong> To facilitate setting more complex config items, the value of an
+environment variable is first parsed as JSON, falling back to a string if the
+parse fails.</p>
+<p>This means, if you so desired, you could override all book metadata when
+building the book with something like</p>
+<pre><code class="language-shell">$ export MDBOOK_BOOK='{"title": "My Awesome Book", "authors": ["Michael-F-Bryan"]}'
+$ mdbook build
+</code></pre>
+</blockquote>
+<p>The latter case may be useful in situations where <code>mdbook</code> is invoked from a
+script or CI, where it sometimes isn't possible to update the <code>book.toml</code> before
+building.</p>

+<li><strong>description:</strong> A description for the book, which is added as meta
+information in the html <code>&lt;head&gt;</code> of each page</li>
+<li><strong>src:</strong> By default, the source directory is found in the directory named
+<code>src</code> directly under the root folder. But this is configurable with the <code>src</code>
+key in the configuration file.</li>
+<li><strong>language:</strong> The main language of the book, which is used as a language attribute <code>&lt;html lang="en"&gt;</code> for example.
+This is also used to derive the direction of text (RTL, LTR) within the book.</li>
+<li><strong>text-direction</strong>: The direction of text in the book: Left-to-right (LTR) or Right-to-left (RTL). Possible values: <code>ltr</code>, <code>rtl</code>.

+<p>Preprocessors are extensions that can modify the raw Markdown source before it gets sent to the renderer.</p>
+<p>The following preprocessors are built-in and included by default:</p>
+<ul>
+<li><code>links</code>: Expands the <code>{{ #playground }}</code>, <code>{{ #include }}</code>, and <code>{{ #rustdoc_include }}</code> handlebars
+helpers in a chapter to include the contents of a file.
+See <a href="../mdbook.html#including-files">Including files</a> for more.</li>
+<li><code>index</code>: Convert all chapter files named <code>README.md</code> into <code>index.md</code>. That is
+to say, all <code>README.md</code> would be rendered to an index file <code>index.html</code> in the
+rendered book.</li>
+</ul>
+<p>The built-in preprocessors can be disabled with the <a href="general.html#build-options"><code>build.use-default-preprocessors</code></a> config option.</p>
+<p>The community has developed several preprocessors.
+See the <a href="https://github.com/rust-lang/mdBook/wiki/Third-party-plugins">Third Party Plugins</a> wiki page for a list of available preprocessors.</p>
+<p>For information on how to create a new preprocessor, see the <a href="../../for_developers/preprocessors.html">Preprocessors for Developers</a> chapter.</p>
+<h2 id="custom-preprocessor-configuration"><a class="header" href="#custom-preprocessor-configuration">Custom Preprocessor Configuration</a></h2>
+<p>Preprocessors can be added by including a <code>preprocessor</code> table in <code>book.toml</code> with the name of the preprocessor.
+For example, if you have a preprocessor called <code>mdbook-example</code>, then you can include it with:</p>
+<pre><code class="language-toml">[preprocessor.example]
+</code></pre>
+<p>With this table, mdBook will execute the <code>mdbook-example</code> preprocessor.</p>
+<p>This table can include additional key-value pairs that are specific to the preprocessor.
+For example, if our example preprocessor needed some extra configuration options:</p>
+<pre><code class="language-toml">[preprocessor.example]
+some-extra-feature = true
+</code></pre>
+<h2 id="locking-a-preprocessor-dependency-to-a-renderer"><a class="header" href="#locking-a-preprocessor-dependency-to-a-renderer">Locking a Preprocessor dependency to a renderer</a></h2>
+<p>You can explicitly specify that a preprocessor should run for a renderer by
+binding the two together.</p>
+<pre><code class="language-toml">[preprocessor.example]
+renderers = ["html"]  # example preprocessor only runs with the HTML renderer
+</code></pre>
+<h2 id="provide-your-own-command"><a class="header" href="#provide-your-own-command">Provide Your Own Command</a></h2>
+<p>By default when you add a <code>[preprocessor.foo]</code> table to your <code>book.toml</code> file,
+<code>mdbook</code> will try to invoke the <code>mdbook-foo</code> executable. If you want to use a
+different program name or pass in command-line arguments, this behaviour can
+be overridden by adding a <code>command</code> field.</p>
+<pre><code class="language-toml">[preprocessor.random]
+command = "python random.py"
+</code></pre>
+<h2 id="require-a-certain-order"><a class="header" href="#require-a-certain-order">Require A Certain Order</a></h2>
+<p>The order in which preprocessors are run can be controlled with the <code>before</code> and <code>after</code> fields.
+For example, suppose you want your <code>linenos</code> preprocessor to process lines that may have been <code>{{#include}}</code>d; then you want it to run after the built-in <code>links</code> preprocessor, which you can require using either the <code>before</code> or <code>after</code> field:</p>
+<pre><code class="language-toml">[preprocessor.linenos]
+after = [ "links" ]
+</code></pre>
+<p>or</p>
+<pre><code class="language-toml">[preprocessor.links]
+before = [ "linenos" ]
+</code></pre>
+<p>It would also be possible, though redundant, to specify both of the above in the same config file.</p>
+<p>Preprocessors having the same priority specified through <code>before</code> and <code>after</code> are sorted by name.
+Any infinite loops will be detected and produce an error.</p>

+<p>Renderers (also called "backends") are responsible for creating the output of the book.</p>
+<p>The following backends are built-in:</p>
+<ul>
+<li><a href="#html-renderer-options"><code>html</code></a> — This renders the book to HTML.
+This is enabled by default if no other <code>[output]</code> tables are defined in <code>book.toml</code>.</li>
+<li><a href="#markdown-renderer"><code>markdown</code></a> — This outputs the book as markdown after running the preprocessors.
+This is useful for debugging preprocessors.</li>
+</ul>
+<p>The community has developed several backends.
+See the <a href="https://github.com/rust-lang/mdBook/wiki/Third-party-plugins">Third Party Plugins</a> wiki page for a list of available backends.</p>
+<p>For information on how to create a new backend, see the <a href="../../for_developers/backends.html">Backends for Developers</a> chapter.</p>
+<h2 id="output-tables"><a class="header" href="#output-tables">Output tables</a></h2>
+<p>Backends can be added by including a <code>output</code> table in <code>book.toml</code> with the name of the backend.
+For example, if you have a backend called <code>mdbook-wordcount</code>, then you can include it with:</p>
+<pre><code class="language-toml">[output.wordcount]
+</code></pre>
+<p>With this table, mdBook will execute the <code>mdbook-wordcount</code> backend.</p>
+<p>This table can include additional key-value pairs that are specific to the backend.
+For example, if our example backend needed some extra configuration options:</p>
+<pre><code class="language-toml">[output.wordcount]
+ignores = ["Example Chapter"]
+</code></pre>
+<p>If you define any <code>[output]</code> tables, then the <code>html</code> backend is not enabled by default.
+If you want to keep the <code>html</code> backend running, then just include it in the <code>book.toml</code> file.
+For example:</p>
+<pre><code class="language-toml">[book]
+title = "My Awesome Book"
+
+[output.wordcount]
+
+[output.html]
+</code></pre>
+<p>If more than one <code>output</code> table is included, this changes the behavior for the layout of the output directory.
+If there is only one backend, then it places its output directly in the <code>book</code> directory (see <a href="general.html#build-options"><code>build.build-dir</code></a> to override this location).
+If there is more than one backend, then each backend is placed in a separate directory underneath <code>book</code>.
+For example, the above would have directories <code>book/html</code> and <code>book/wordcount</code>.</p>
+<h3 id="custom-backend-commands"><a class="header" href="#custom-backend-commands">Custom backend commands</a></h3>
+<p>By default when you add an <code>[output.foo]</code> table to your <code>book.toml</code> file,
+<code>mdbook</code> will try to invoke the <code>mdbook-foo</code> executable.
+If you want to use a different program name or pass in command-line arguments,
+this behaviour can be overridden by adding a <code>command</code> field.</p>
+<pre><code class="language-toml">[output.random]
+command = "python random.py"
+</code></pre>
+<h3 id="optional-backends"><a class="header" href="#optional-backends">Optional backends</a></h3>
+<p>If you enable a backend that isn't installed, the default behavior is to throw an error.
+This behavior can be changed by marking the backend as optional:</p>
+<pre><code class="language-toml">[output.wordcount]
+optional = true
+</code></pre>
+<p>This demotes the error to a warning.</p>
+<h2 id="html-renderer-options"><a class="header" href="#html-renderer-options">HTML renderer options</a></h2>
+<p>The HTML renderer has a variety of options detailed below.
+They should be specified in the <code>[output.html]</code> table of the <code>book.toml</code> file.</p>
+<pre><code class="language-toml"># Example book.toml file with all output options.

+</code></pre>
+<p>The following configuration options are available:</p>
+<ul>
+<li><strong>theme:</strong> mdBook comes with a default theme and all the resource files needed
+for it. But if this option is set, mdBook will selectively overwrite the theme
+files with the ones found in the specified folder.</li>
+<li><strong>default-theme:</strong> The theme color scheme to select by default in the
+'Change Theme' dropdown. Defaults to <code>light</code>.</li>
+<li><strong>preferred-dark-theme:</strong> The default dark theme. This theme will be used if
+the browser requests the dark version of the site via the
+<a href="https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme">'prefers-color-scheme'</a>
+CSS media query. Defaults to <code>navy</code>.</li>
+<li><strong>curly-quotes:</strong> Convert straight quotes to curly quotes, except for those
+that occur in code blocks and code spans. Defaults to <code>false</code>.</li>
+<li><strong>mathjax-support:</strong> Adds support for <a href="../mathjax.html">MathJax</a>. Defaults to
+<code>false</code>.</li>
+<li><strong>copy-fonts:</strong> (<strong>Deprecated</strong>) If <code>true</code> (the default), mdBook uses its built-in fonts which are copied to the output directory.
+If <code>false</code>, the built-in fonts will not be used.
+This option is deprecated. If you want to define your own custom fonts,
+create a <code>theme/fonts/fonts.css</code> file and store the fonts in the <code>theme/fonts/</code> directory.</li>
+<li><strong>google-analytics:</strong> This field has been deprecated and will be removed in a future release.
+Use the <code>theme/head.hbs</code> file to add the appropriate Google Analytics code instead.</li>
+<li><strong>additional-css:</strong> If you need to slightly change the appearance of your book
+without overwriting the whole style, you can specify a set of stylesheets that
+will be loaded after the default ones where you can surgically change the
+style.</li>
+<li><strong>additional-js:</strong> If you need to add some behaviour to your book without
+removing the current behaviour, you can specify a set of JavaScript files that
+will be loaded alongside the default one.</li>
+<li><strong>no-section-label:</strong> mdBook by defaults adds numeric section labels in the table of
+contents column. For example, "1.", "2.1". Set this option to true to disable
+those labels. Defaults to <code>false</code>.</li>
+<li><strong>git-repository-url:</strong>  A url to the git repository for the book. If provided
+an icon link will be output in the menu bar of the book.</li>
+<li><strong>git-repository-icon:</strong> The FontAwesome icon class to use for the git
+repository link. Defaults to <code>fa-github</code> which looks like <i class="fa fa-github"></i>.
+If you are not using GitHub, another option to consider is <code>fa-code-fork</code> which looks like <i class="fa fa-code-fork"></i>.</li>
+<li><strong>edit-url-template:</strong> Edit url template, when provided shows a
+"Suggest an edit" button (which looks like <i class="fa fa-edit"></i>) for directly jumping to editing the currently
+viewed page. For e.g. GitHub projects set this to
+<code>https://github.com/&lt;owner&gt;/&lt;repo&gt;/edit/&lt;branch&gt;/{path}</code> or for
+Bitbucket projects set it to
+<code>https://bitbucket.org/&lt;owner&gt;/&lt;repo&gt;/src/&lt;branch&gt;/{path}?mode=edit</code>
+where {path} will be replaced with the full path of the file in the
+repository.</li>
+<li><strong>input-404:</strong> The name of the markdown file used for missing files.
+The corresponding output file will be the same, with the extension replaced with <code>html</code>.
+Defaults to <code>404.md</code>.</li>
+<li><strong>site-url:</strong> The url where the book will be hosted. This is required to ensure
+navigation links and script/css imports in the 404 file work correctly, even when accessing
+urls in subdirectories. Defaults to <code>/</code>. If <code>site-url</code> is set,
+make sure to use document relative links for your assets, meaning they should not start with <code>/</code>.</li>
+<li><strong>cname:</strong> The DNS subdomain or apex domain at which your book will be hosted.
+This string will be written to a file named CNAME in the root of your site, as
+required by GitHub Pages (see <a href="https://docs.github.com/en/github/working-with-github-pages/managing-a-custom-domain-for-your-github-pages-site"><em>Managing a custom domain for your GitHub Pages
+site</em></a>).</li>

+<p>mdBook's <a href="https://github.com/raphlinus/pulldown-cmark">parser</a> adheres to the <a href="https://commonmark.org/">CommonMark</a> specification with some extensions described below.
+You can take a quick <a href="https://commonmark.org/help/tutorial/">tutorial</a>,
+or <a href="https://spec.commonmark.org/dingus/">try out</a> CommonMark in real time. A complete Markdown overview is out of scope for
+this documentation, but below is a high level overview of some of the basics. For a more in-depth experience, check out the
+<a href="https://www.markdownguide.org">Markdown Guide</a>.</p>
+<h2 id="text-and-paragraphs"><a class="header" href="#text-and-paragraphs">Text and Paragraphs</a></h2>
+<p>Text is rendered relatively predictably:</p>
+<pre><code class="language-markdown">Here is a line of text.
+
+This is a new line.
+</code></pre>
+<p>Will look like you might expect:</p>
+<p>Here is a line of text.</p>
+<p>This is a new line.</p>
+<h2 id="headings"><a class="header" href="#headings">Headings</a></h2>
+<p>Headings use the <code>#</code> marker and should be on a line by themselves. More <code>#</code> mean smaller headings:</p>
+<pre><code class="language-markdown">### A heading 
+
+Some text.
+
+#### A smaller heading 
+
+More text.
+</code></pre>
+<h3 id="a-heading"><a class="header" href="#a-heading">A heading</a></h3>
+<p>Some text.</p>
+<h4 id="a-smaller-heading"><a class="header" href="#a-smaller-heading">A smaller heading</a></h4>
+<p>More text.</p>
+<h2 id="lists"><a class="header" href="#lists">Lists</a></h2>
+<p>Lists can be unordered or ordered. Ordered lists will order automatically:</p>
+<pre><code class="language-markdown">* milk
+* eggs
+* butter
+
+1. carrots
+1. celery
+1. radishes
+</code></pre>
+<ul>
+<li>milk</li>
+<li>eggs</li>
+<li>butter</li>
+</ul>
+<ol>
+<li>carrots</li>
+<li>celery</li>
+<li>radishes</li>
+</ol>
+<h2 id="links"><a class="header" href="#links">Links</a></h2>
+<p>Linking to a URL or local file is easy:</p>
+<pre><code class="language-markdown">Use [mdBook](https://github.com/rust-lang/mdBook). 
+
+Read about [mdBook](mdbook.md).
+
+A bare url: &lt;https://www.rust-lang.org&gt;.
+</code></pre>
+<p>Use <a href="https://github.com/rust-lang/mdBook">mdBook</a>.</p>
+<p>Read about <a href="mdbook.html">mdBook</a>.</p>
+<p>A bare url: <a href="https://www.rust-lang.org">https://www.rust-lang.org</a>.</p>
+<hr />
+<p>Relative links that end with <code>.md</code> will be converted to the <code>.html</code> extension.
+It is recommended to use <code>.md</code> links when possible.
+This is useful when viewing the Markdown file outside of mdBook, for example on GitHub or GitLab which render Markdown automatically.</p>
+<p>Links to <code>README.md</code> will be converted to <code>index.html</code>.
+This is done since some services like GitHub render README files automatically, but web servers typically expect the root file to be called <code>index.html</code>.</p>
+<p>You can link to individual headings with <code>#</code> fragments.
+For example, <code>mdbook.md#text-and-paragraphs</code> would link to the <a href="#text-and-paragraphs">Text and Paragraphs</a> section above.
+The ID is created by transforming the heading such as converting to lowercase and replacing spaces with dashes.
+You can click on any heading and look at the URL in your browser to see what the fragment looks like.</p>
+<h2 id="images"><a class="header" href="#images">Images</a></h2>
+<p>Including images is simply a matter of including a link to them, much like in the <em>Links</em> section above. The following markdown
+includes the Rust logo SVG image found in the <code>images</code> directory at the same level as this file:</p>
+<pre><code class="language-markdown">![The Rust Logo](images/rust-logo-blk.svg)
+</code></pre>
+<p>Produces the following HTML when built with mdBook:</p>
+<pre><code class="language-html">&lt;p&gt;&lt;img src="images/rust-logo-blk.svg" alt="The Rust Logo" /&gt;&lt;/p&gt;
+</code></pre>
+<p>Which, of course displays the image like so:</p>
+<p><img src="images/rust-logo-blk.svg" alt="The Rust Logo" /></p>
+<h2 id="extensions"><a class="header" href="#extensions">Extensions</a></h2>
+<p>mdBook has several extensions beyond the standard CommonMark specification.</p>
+<h3 id="strikethrough"><a class="header" href="#strikethrough">Strikethrough</a></h3>
+<p>Text may be rendered with a horizontal line through the center by wrapping the
+text with one or two tilde characters on each side:</p>
+<pre><code class="language-text">An example of ~~strikethrough text~~.
+</code></pre>
+<p>This example will render as:</p>
+<blockquote>
+<p>An example of <del>strikethrough text</del>.</p>
+</blockquote>
+<p>This follows the <a href="https://github.github.com/gfm/#strikethrough-extension-">GitHub Strikethrough extension</a>.</p>
+<h3 id="footnotes"><a class="header" href="#footnotes">Footnotes</a></h3>
+<p>A footnote generates a small numbered link in the text which when clicked
+takes the reader to the footnote text at the bottom of the item. The footnote
+label is written similarly to a link reference with a caret at the front. The
+footnote text is written like a link reference definition, with the text
+following the label. Example:</p>
+<pre><code class="language-text">This is an example of a footnote[^note].
+
+[^note]: This text is the contents of the footnote, which will be rendered
+    towards the bottom.
+</code></pre>
+<p>This example will render as:</p>
+<blockquote>
+<p>This is an example of a footnote<sup class="footnote-reference"><a href="#note">1</a></sup>.</p>
+<div class="footnote-definition" id="note"><sup class="footnote-definition-label">1</sup>
+<p>This text is the contents of the footnote, which will be rendered
+towards the bottom.</p>
+</div>
+</blockquote>
+<p>The footnotes are automatically numbered based on the order the footnotes are
+written.</p>
+<h3 id="tables"><a class="header" href="#tables">Tables</a></h3>
+<p>Tables can be written using pipes and dashes to draw the rows and columns of
+the table. These will be translated to HTML table matching the shape. Example:</p>
+<pre><code class="language-text">| Header1 | Header2 |
+|---------|---------|
+| abc     | def     |
+</code></pre>
+<p>This example will render similarly to this:</p>
+<div class="table-wrapper"><table><thead><tr><th>Header1</th><th>Header2</th></tr></thead><tbody>
+<tr><td>abc</td><td>def</td></tr>
+</tbody></table>
+</div>
+<p>See the specification for the <a href="https://github.github.com/gfm/#tables-extension-">GitHub Tables extension</a> for more
+details on the exact syntax supported.</p>
+<h3 id="task-lists"><a class="header" href="#task-lists">Task lists</a></h3>
+<p>Task lists can be used as a checklist of items that have been completed.
+Example:</p>
+<pre><code class="language-md">- [x] Complete task
+- [ ] Incomplete task
+</code></pre>
+<p>This will render as:</p>
+<blockquote>
+<ul>
+<li><input disabled="" type="checkbox" checked=""/>
+Complete task</li>
+<li><input disabled="" type="checkbox"/>
+Incomplete task</li>
+</ul>
+</blockquote>
+<p>See the specification for the <a href="https://github.github.com/gfm/#task-list-items-extension-">task list extension</a> for more details.</p>
+<h3 id="smart-punctuation"><a class="header" href="#smart-punctuation">Smart punctuation</a></h3>
+<p>Some ASCII punctuation sequences will be automatically turned into fancy Unicode
+characters:</p>
+<div class="table-wrapper"><table><thead><tr><th>ASCII sequence</th><th>Unicode</th></tr></thead><tbody>
+<tr><td><code>--</code></td><td>–</td></tr>
+<tr><td><code>---</code></td><td>—</td></tr>
+<tr><td><code>...</code></td><td>…</td></tr>
+<tr><td><code>"</code></td><td>“ or ”, depending on context</td></tr>
+<tr><td><code>'</code></td><td>‘ or ’, depending on context</td></tr>
+</tbody></table>
+</div>
+<p>So, no need to manually enter those Unicode characters!</p>
+<p>This feature is disabled by default.
+To enable it, see the <a href="configuration/renderers.html#html-renderer-options"><code>output.html.curly-quotes</code></a> config option.</p>
+<h3 id="heading-attributes"><a class="header" href="#heading-attributes">Heading attributes</a></h3>
+<p>Headings can have a custom HTML ID and classes. This lets you maintain the same ID even if you change the heading's text, it also lets you add multiple classes in the heading.</p>
+<p>Example:</p>
+<pre><code class="language-md"># Example heading { #first .class1 .class2 }
+</code></pre>
+<p>This makes the level 1 heading with the content <code>Example heading</code>, ID <code>first</code>, and classes <code>class1</code> and <code>class2</code>. Note that the attributes should be space-separated.</p>
+<p>More information can be found in the <a href="https://github.com/raphlinus/pulldown-cmark/blob/master/pulldown-cmark/specs/heading_attrs.txt">heading attrs spec page</a>.</p>

+<p>mdBook has optional support for math equations through
+<a href="https://www.mathjax.org/">MathJax</a>.</p>
+<p>To enable MathJax, you need to add the <code>mathjax-support</code> key to your <code>book.toml</code>
+under the <code>output.html</code> section.</p>
+<pre><code class="language-toml">[output.html]
+mathjax-support = true
+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> The usual delimiters MathJax uses are not yet supported. You can't
+currently use <code>$$ ... $$</code> as delimiters and the <code>\[ ... \]</code> delimiters need an
+extra backslash to work. Hopefully this limitation will be lifted soon.</p>
+</blockquote>
+<blockquote>
+<p><strong>Note:</strong> When you use double backslashes in MathJax blocks (for example in
+commands such as <code>\begin{cases} \frac 1 2 \\ \frac 3 4 \end{cases}</code>) you need
+to add <em>two extra</em> backslashes (e.g., <code>\begin{cases} \frac 1 2 \\\\ \frac 3 4 \end{cases}</code>).</p>
+</blockquote>
+<h3 id="inline-equations"><a class="header" href="#inline-equations">Inline equations</a></h3>
+<p>Inline equations are delimited by <code>\\(</code> and <code>\\)</code>. So for example, to render the
+following inline equation \( \int x dx = \frac{x^2}{2} + C \) you would write
+the following:</p>
+<pre><code>\\( \int x dx = \frac{x^2}{2} + C \\)
+</code></pre>
+<h3 id="block-equations"><a class="header" href="#block-equations">Block equations</a></h3>
+<p>Block equations are delimited by <code>\\[</code> and <code>\\]</code>. To render the following
+equation</p>
+<p>\[ \mu = \frac{1}{N} \sum_{i=0} x_i \]</p>
+<p>you would write:</p>
+<pre><code class="language-bash">\\[ \mu = \frac{1}{N} \sum_{i=0} x_i \\]

+<h2 id="hiding-code-lines"><a class="header" href="#hiding-code-lines">Hiding code lines</a></h2>
+<p>There is a feature in mdBook that lets you hide code lines by prepending them with a specific prefix.</p>
+<p>For the Rust language, you can use the <code>#</code> character as a prefix which will hide lines <a href="https://doc.rust-lang.org/stable/rustdoc/write-documentation/documentation-tests.html#hiding-portions-of-the-example">like you would with Rustdoc</a>.</p>
+<pre><code class="language-bash"># fn main() {
+    let x = 5;
+    let y = 6;
+
+    println!("{}", x + y);
+# }
+</code></pre>
+<p>Will render as</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">fn main() {
+</span>    let x = 5;
+    let y = 6;
+
+    println!("{}", x + y);
+<span class="boring">}</span></code></pre></pre>
+<p>When you tap or hover the mouse over the code block, there will be an eyeball icon (<i class="fa fa-eye"></i>) which will toggle the visibility of the hidden lines.</p>
+<p>By default, this only works for code examples that are annotated with <code>rust</code>.
+However, you can define custom prefixes for other languages by adding a new line-hiding prefix in your <code>book.toml</code> with the language name and prefix character(s):</p>
+<pre><code class="language-toml">[output.html.code.hidelines]
+python = "~"
+</code></pre>
+<p>The prefix will hide any lines that begin with the given prefix. With the python prefix shown above, this:</p>
+<pre><code class="language-bash">~hidden()
+nothidden():
+~    hidden()
+    ~hidden()
+    nothidden()
+</code></pre>
+<p>will render as</p>
+<pre><code class="language-python"><span class="boring">hidden()
+</span>nothidden():
+<span class="boring">    hidden()
+</span><span class="boring">    hidden()
+</span>    nothidden()
+</code></pre>
+<p>This behavior can be overridden locally with a different prefix. This has the same effect as above:</p>
+<pre><code class="language-markdown">```python,hidelines=!!!
+!!!hidden()
+nothidden():
+!!!    hidden()
+    !!!hidden()
+    nothidden()
+```
+</code></pre>
+<h2 id="rust-playground"><a class="header" href="#rust-playground">Rust Playground</a></h2>
+<p>Rust language code blocks will automatically get a play button (<i class="fa fa-play"></i>) which will execute the code and display the output just below the code block.
+This works by sending the code to the <a href="https://play.rust-lang.org/">Rust Playground</a>.</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">#![allow(unused)]
+</span><span class="boring">fn main() {
+</span>println!("Hello, World!");
+<span class="boring">}</span></code></pre></pre>
+<p>If there is no <code>main</code> function, then the code is automatically wrapped inside one.</p>
+<p>If you wish to disable the play button for a code block, you can include the <code>noplayground</code> option on the code block like this:</p>
+<pre><code class="language-markdown">```rust,noplayground
+let mut name = String::new();
+std::io::stdin().read_line(&amp;mut name).expect("failed to read line");
+println!("Hello {}!", name);
+```
+</code></pre>
+<p>Or, if you wish to disable the play button for all code blocks in your book, you can write the config to the <code>book.toml</code> like this.</p>
+<pre><code class="language-toml">[output.html.playground]
+runnable = false
+</code></pre>
+<h2 id="rust-code-block-attributes"><a class="header" href="#rust-code-block-attributes">Rust code block attributes</a></h2>
+<p>Additional attributes can be included in Rust code blocks with comma, space, or tab-separated terms just after the language term. For example:</p>
+<pre><code class="language-markdown">```rust,ignore
+# This example won't be tested.
+panic!("oops!");
+```
+</code></pre>
+<p>These are particularly important when using <a href="../cli/test.html"><code>mdbook test</code></a> to test Rust examples.
+These use the same attributes as <a href="https://doc.rust-lang.org/rustdoc/documentation-tests.html#attributes">rustdoc attributes</a>, with a few additions:</p>
+<ul>
+<li><code>editable</code> — Enables the <a href="theme/editor.html">editor</a>.</li>
+<li><code>noplayground</code> — Removes the play button, but will still be tested.</li>
+<li><code>mdbook-runnable</code> — Forces the play button to be displayed.
+This is intended to be combined with the <code>ignore</code> attribute for examples that should not be tested, but you want to allow the reader to run.</li>
+<li><code>ignore</code> — Will not be tested and no play button is shown, but it is still highlighted as Rust syntax.</li>
+<li><code>should_panic</code> — When executed, it should produce a panic.</li>
+<li><code>no_run</code> — The code is compiled when tested, but it is not run.
+The play button is also not shown.</li>
+<li><code>compile_fail</code> — The code should fail to compile.</li>
+<li><code>edition2015</code>, <code>edition2018</code>, <code>edition2021</code> — Forces the use of a specific Rust edition.
+See <a href="configuration/general.html#rust-options"><code>rust.edition</code></a> to set this globally.</li>
+</ul>
+<h2 id="including-files"><a class="header" href="#including-files">Including files</a></h2>
+<p>With the following syntax, you can include files into your book:</p>
+<pre><code class="language-hbs">{{#include file.rs}}
+</code></pre>
+<p>The path to the file has to be relative from the current source file.</p>
+<p>mdBook will interpret included files as Markdown. Since the include command
+is usually used for inserting code snippets and examples, you will often
+wrap the command with <code>```</code> to display the file contents without
+interpreting them.</p>
+<pre><code class="language-hbs">```
+{{#include file.rs}}
+```
+</code></pre>
+<h2 id="including-portions-of-a-file"><a class="header" href="#including-portions-of-a-file">Including portions of a file</a></h2>
+<p>Often you only need a specific part of the file, e.g. relevant lines for an
+example. We support four different modes of partial includes:</p>
+<pre><code class="language-hbs">{{#include file.rs:2}}
+{{#include file.rs::10}}
+{{#include file.rs:2:}}
+{{#include file.rs:2:10}}
+</code></pre>
+<p>The first command only includes the second line from file <code>file.rs</code>. The second
+command includes all lines up to line 10, i.e. the lines from 11 till the end of
+the file are omitted. The third command includes all lines from line 2, i.e. the
+first line is omitted. The last command includes the excerpt of <code>file.rs</code>
+consisting of lines 2 to 10.</p>
+<p>To avoid breaking your book when modifying included files, you can also
+include a specific section using anchors instead of line numbers.
+An anchor is a pair of matching lines. The line beginning an anchor must
+match the regex <code>ANCHOR:\s*[\w_-]+</code> and similarly the ending line must match
+the regex <code>ANCHOR_END:\s*[\w_-]+</code>. This allows you to put anchors in
+any kind of commented line.</p>
+<p>Consider the following file to include:</p>
+<pre><code class="language-rs">/* ANCHOR: all */
+
+// ANCHOR: component
+struct Paddle {
+    hello: f32,
+}
+// ANCHOR_END: component
+
+////////// ANCHOR: system
+impl System for MySystem { ... }
+////////// ANCHOR_END: system
+
+/* ANCHOR_END: all */
+</code></pre>
+<p>Then in the book, all you have to do is:</p>
+<pre><code class="language-hbs">Here is a component:
+```rust,no_run,noplayground
+{{#include file.rs:component}}
+```
+
+Here is a system:
+```rust,no_run,noplayground
+{{#include file.rs:system}}
+```
+
+This is the full file.
+```rust,no_run,noplayground
+{{#include file.rs:all}}
+```
+</code></pre>
+<p>Lines containing anchor patterns inside the included anchor are ignored.</p>
+<h2 id="including-a-file-but-initially-hiding-all-except-specified-lines"><a class="header" href="#including-a-file-but-initially-hiding-all-except-specified-lines">Including a file but initially hiding all except specified lines</a></h2>
+<p>The <code>rustdoc_include</code> helper is for including code from external Rust files that contain complete
+examples, but only initially showing particular lines specified with line numbers or anchors in the
+same way as with <code>include</code>.</p>
+<p>The lines not in the line number range or between the anchors will still be included, but they will
+be prefaced with <code>#</code>. This way, a reader can expand the snippet to see the complete example, and
+Rustdoc will use the complete example when you run <code>mdbook test</code>.</p>
+<p>For example, consider a file named <code>file.rs</code> that contains this Rust program:</p>
+<pre><pre class="playground"><code class="language-rust edition2018">fn main() {
+    let x = add_one(2);
+    assert_eq!(x, 3);
+}
+
+fn add_one(num: i32) -&gt; i32 {
+    num + 1
+}</code></pre></pre>
+<p>We can include a snippet that initially shows only line 2 by using this syntax:</p>
+<pre><code class="language-hbs">To call the `add_one` function, we pass it an `i32` and bind the returned value to `x`:
+
+```rust
+{{#rustdoc_include file.rs:2}}
+```
+</code></pre>
+<p>This would have the same effect as if we had manually inserted the code and hidden all but line 2
+using <code>#</code>:</p>
+<pre><code class="language-hbs">To call the `add_one` function, we pass it an `i32` and bind the returned value to `x`:
+
+```rust
+# fn main() {
+    let x = add_one(2);
+#     assert_eq!(x, 3);
+# }
+#
+# fn add_one(num: i32) -&gt; i32 {
+#     num + 1
+# }
+```
+</code></pre>
+<p>That is, it looks like this (click the "expand" icon to see the rest of the file):</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">fn main() {
+</span>    let x = add_one(2);
+<span class="boring">    assert_eq!(x, 3);
+</span><span class="boring">}
+</span><span class="boring">
+</span><span class="boring">fn add_one(num: i32) -&gt; i32 {
+</span><span class="boring">    num + 1
+</span><span class="boring">}</span></code></pre></pre>
+<h2 id="inserting-runnable-rust-files"><a class="header" href="#inserting-runnable-rust-files">Inserting runnable Rust files</a></h2>
+<p>With the following syntax, you can insert runnable Rust files into your book:</p>
+<pre><code class="language-hbs">{{#playground file.rs}}
+</code></pre>
+<p>The path to the Rust file has to be relative from the current source file.</p>
+<p>When play is clicked, the code snippet will be sent to the <a href="https://play.rust-lang.org/">Rust Playground</a> to be
+compiled and run. The result is sent back and displayed directly underneath the
+code.</p>
+<p>Here is what a rendered code snippet looks like:</p>
+<pre><pre class="playground"><code class="language-rust edition2018">fn main() {
+    println!("Hello World!");
+<span class="boring">
+</span><span class="boring">    // You can even hide lines! :D
+</span><span class="boring">    println!("I am hidden! Expand the code snippet to see me");
+</span>}</code></pre></pre>
+<p>Any additional values passed after the filename will be included as attributes of the code block.
+For example <code>{{#playground example.rs editable}}</code> will create the code block like the following:</p>
+<pre><code class="language-markdown">```rust,editable
+# Contents of example.rs here.
+```
+</code></pre>
+<p>And the <code>editable</code> attribute will enable the <a href="theme/editor.html">editor</a> as described at <a href="#rust-code-block-attributes">Rust code block attributes</a>.</p>
+<h2 id="controlling-page-title"><a class="header" href="#controlling-page-title">Controlling page &lt;title&gt;</a></h2>
+<p>A chapter can set a &lt;title&gt; that is different from its entry in the table of

+<p>The summary file is used by mdBook to know what chapters to include, in what
+order they should appear, what their hierarchy is and where the source files
+are. Without this file, there is no book.</p>
+<p>This markdown file must be named <code>SUMMARY.md</code>. Its formatting
+is very strict and must follow the structure outlined below to allow for easy
+parsing. Any element not specified below, be it formatting or textual, is likely
+to be ignored at best, or may cause an error when attempting to build the book.</p>
+<h3 id="structure"><a class="header" href="#structure">Structure</a></h3>
+<ol>
+<li>
+<p><em><strong>Title</strong></em> - While optional, it's common practice to begin with a title, generally <code
+class="language-markdown"># Summary</code>. This is ignored by the parser however, and
+can be omitted.</p>
+<pre><code class="language-markdown"># Summary
+</code></pre>
+</li>
+<li>
+<p><em><strong>Prefix Chapter</strong></em> - Before the main numbered chapters, prefix chapters can be added
+that will not be numbered. This is useful for forewords,
+introductions, etc. There are, however, some constraints. Prefix chapters cannot be
+nested; they should all be on the root level. And you cannot add
+prefix chapters once you have added numbered chapters.</p>
+<pre><code class="language-markdown">[A Prefix Chapter](relative/path/to/markdown.md)
+
+- [First Chapter](relative/path/to/markdown2.md)
+</code></pre>
+</li>
+<li>
+<p><em><strong>Part Title</strong></em> -
+Level 1 headers can be used as a title for the following numbered chapters.
+This can be used to logically separate different sections of the book.
+The title is rendered as unclickable text.
+Titles are optional, and the numbered chapters can be broken into as many parts as desired.
+Part titles must be h1 headers (one <code>#</code>), other heading levels are ignored.</p>
+<pre><code class="language-markdown"># My Part Title
+
+- [First Chapter](relative/path/to/markdown.md)
+</code></pre>
+</li>
+<li>
+<p><em><strong>Numbered Chapter</strong></em> - Numbered chapters outline the main content of the book
+and can be nested, resulting in a nice hierarchy
+(chapters, sub-chapters, etc.).</p>
+<pre><code class="language-markdown"># Title of Part
+
+- [First Chapter](relative/path/to/markdown.md)
+- [Second Chapter](relative/path/to/markdown2.md)
+   - [Sub Chapter](relative/path/to/markdown3.md)
+
+# Title of Another Part
+
+- [Another Chapter](relative/path/to/markdown4.md)
+</code></pre>
+<p>Numbered chapters can be denoted with either <code>-</code> or <code>*</code> (do not mix delimiters).</p>
+</li>
+<li>
+<p><em><strong>Suffix Chapter</strong></em> - Like prefix chapters, suffix chapters are unnumbered, but they come after
+numbered chapters.</p>
+<pre><code class="language-markdown">- [Last Chapter](relative/path/to/markdown.md)
+
+[Title of Suffix Chapter](relative/path/to/markdown2.md)
+</code></pre>
+</li>
+<li>
+<p><em><strong>Draft chapters</strong></em> - Draft chapters are chapters without a file and thus content.
+The purpose of a draft chapter is to signal future chapters still to be written.
+Or when still laying out the structure of the book to avoid creating the files
+while you are still changing the structure of the book a lot.
+Draft chapters will be rendered in the HTML renderer as disabled links in the table
+of contents, as you can see for the next chapter in the table of contents on the left.
+Draft chapters are written like normal chapters but without writing the path to the file.</p>
+<pre><code class="language-markdown">- [Draft Chapter]()
+</code></pre>
+</li>
+<li>
+<p><em><strong>Separators</strong></em> - Separators can be added before, in between, and after any other element. They result
+in an HTML rendered line in the built table of contents.  A separator is
+a line containing exclusively dashes and at least three of them: <code>---</code>.</p>
+<pre><code class="language-markdown"># My Part Title
+
+[A Prefix Chapter](relative/path/to/markdown.md)

+<p>In addition to providing runnable code playgrounds, mdBook optionally allows them
+to be editable. In order to enable editable code blocks, the following needs to
+be added to the <em><strong>book.toml</strong></em>:</p>
+<pre><code class="language-toml">[output.html.playground]
+editable = true
+</code></pre>
+<p>To make a specific block available for editing, the attribute <code>editable</code> needs
+to be added to it:</p>
+<pre><code class="language-markdown">```rust,editable
+fn main() {
+    let number = 5;
+    print!("{}", number);
+}
+```
+</code></pre>
+<p>The above will result in this editable playground:</p>
+<pre><pre class="playground"><code class="language-rust editable edition2018">fn main() {
+    let number = 5;
+    print!("{}", number);
+}</code></pre></pre>
+<p>Note the new <code>Undo Changes</code> button in the editable playgrounds.</p>
+<h2 id="customizing-the-editor"><a class="header" href="#customizing-the-editor">Customizing the Editor</a></h2>
+<p>By default, the editor is the <a href="https://ace.c9.io/">Ace</a> editor, but, if desired,
+the functionality may be overridden by providing a different folder:</p>
+<pre><code class="language-toml">[output.html.playground]
+editable = true
+editor = "/path/to/editor"
+</code></pre>
+<p>Note that for the editor changes to function correctly, the <code>book.js</code> inside of
+the <code>theme</code> folder will need to be overridden as it has some couplings with the
+default Ace editor.</p>

+<p><code>index.hbs</code> is the handlebars template that is used to render the book. The
+markdown files are processed to html and then injected in that template.</p>
+<p>If you want to change the layout or style of your book, chances are that you
+will have to modify this template a little bit. Here is what you need to know.</p>
+<h2 id="data"><a class="header" href="#data">Data</a></h2>
+<p>A lot of data is exposed to the handlebars template with the "context". In the
+handlebars template you can access this information by using</p>
+<pre><code class="language-handlebars">{{name_of_property}}
+</code></pre>
+<p>Here is a list of the properties that are exposed:</p>
+<ul>
+<li>
+<p><em><strong>language</strong></em> Language of the book in the form <code>en</code>, as specified in <code>book.toml</code> (if not specified, defaults to <code>en</code>). To use in <code
+class="language-html">&lt;html lang="{{ language }}"&gt;</code> for example.</p>
+</li>
+<li>
+<p><em><strong>title</strong></em> Title used for the current page. This is identical to <code>{{ chapter_title }} - {{ book_title }}</code> unless <code>book_title</code> is not set in which case it just defaults to the <code>chapter_title</code>.</p>
+</li>
+<li>
+<p><em><strong>book_title</strong></em> Title of the book, as specified in <code>book.toml</code></p>
+</li>
+<li>
+<p><em><strong>chapter_title</strong></em> Title of the current chapter, as listed in <code>SUMMARY.md</code></p>
+</li>
+<li>
+<p><em><strong>path</strong></em> Relative path to the original markdown file from the source
+directory</p>
+</li>
+<li>
+<p><em><strong>content</strong></em> This is the rendered markdown.</p>
+</li>
+<li>
+<p><em><strong>path_to_root</strong></em> This is a path containing exclusively <code>../</code>'s that points
+to the root of the book from the current file. Since the original directory
+structure is maintained, it is useful to prepend relative links with this
+<code>path_to_root</code>.</p>
+</li>
+<li>
+<p><em><strong>chapters</strong></em> Is an array of dictionaries of the form</p>
+<pre><code class="language-json">{"section": "1.2.1", "name": "name of this chapter", "path": "dir/markdown.md"}
+</code></pre>
+<p>containing all the chapters of the book. It is used for example to construct
+the table of contents (sidebar).</p>
+</li>
+</ul>
+<h2 id="handlebars-helpers"><a class="header" href="#handlebars-helpers">Handlebars Helpers</a></h2>
+<p>In addition to the properties you can access, there are some handlebars helpers
+at your disposal.</p>
+<h3 id="1-toc"><a class="header" href="#1-toc">1. toc</a></h3>
+<p>The toc helper is used like this</p>
+<pre><code class="language-handlebars">{{#toc}}{{/toc}}
+</code></pre>
+<p>and outputs something that looks like this, depending on the structure of your
+book</p>
+<pre><code class="language-html">&lt;ul class="chapter"&gt;
+    &lt;li&gt;&lt;a href="link/to/file.html"&gt;Some chapter&lt;/a&gt;&lt;/li&gt;
+    &lt;li&gt;
+        &lt;ul class="section"&gt;
+            &lt;li&gt;&lt;a href="link/to/other_file.html"&gt;Some other Chapter&lt;/a&gt;&lt;/li&gt;
+        &lt;/ul&gt;
+    &lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+<p>If you would like to make a toc with another structure, you have access to the
+chapters property containing all the data. The only limitation at the moment
+is that you would have to do it with JavaScript instead of with a handlebars
+helper.</p>
+<pre><code class="language-html">&lt;script&gt;
+var chapters = {{chapters}};
+// Processing here
+&lt;/script&gt;
+</code></pre>
+<h3 id="2-previous--next"><a class="header" href="#2-previous--next">2. previous / next</a></h3>
+<p>The previous and next helpers expose a <code>link</code> and <code>name</code> property to the
+previous and next chapters.</p>
+<p>They are used like this</p>
+<pre><code class="language-handlebars">{{#previous}}
+    &lt;a href="{{link}}" class="nav-chapters previous"&gt;
+        &lt;i class="fa fa-angle-left"&gt;&lt;/i&gt;
+    &lt;/a&gt;
+{{/previous}}
+</code></pre>
+<p>The inner html will only be rendered if the previous / next chapter exists.
+Of course the inner html can be changed to your liking.</p>
+<hr />
+<p><em>If you would like other properties or helpers exposed, please <a href="https://github.com/rust-lang/mdBook/issues">create a new
+issue</a></em></p>

+<p>The default renderer uses a <a href="https://handlebarsjs.com">handlebars</a> template to
+render your markdown files and comes with a default theme included in the mdBook
+binary.</p>
+<p>The theme is totally customizable, you can selectively replace every file from
+the theme by your own by adding a <code>theme</code> directory next to <code>src</code> folder in your
+project root. Create a new file with the name of the file you want to override
+and now that file will be used instead of the default file.</p>
+<p>Here are the files you can override:</p>
+<ul>
+<li><strong><em>index.hbs</em></strong> is the handlebars template.</li>
+<li><strong><em>head.hbs</em></strong> is appended to the HTML <code>&lt;head&gt;</code> section.</li>
+<li><strong><em>header.hbs</em></strong> content is appended on top of every book page.</li>
+<li><strong><em>css/</em></strong> contains the CSS files for styling the book.
+<ul>
+<li><strong><em>css/chrome.css</em></strong> is for UI elements.</li>
+<li><strong><em>css/general.css</em></strong> is the base styles.</li>
+<li><strong><em>css/print.css</em></strong> is the style for printer output.</li>
+<li><strong><em>css/variables.css</em></strong> contains variables used in other CSS files.</li>
+</ul>
+</li>
+<li><strong><em>book.js</em></strong> is mostly used to add client side functionality, like hiding /
+un-hiding the sidebar, changing the theme, ...</li>
+<li><strong><em>highlight.js</em></strong> is the JavaScript that is used to highlight code snippets,
+you should not need to modify this.</li>
+<li><strong><em>highlight.css</em></strong> is the theme used for the code highlighting.</li>
+<li><strong><em>favicon.svg</em></strong> and <strong><em>favicon.png</em></strong> the favicon that will be used. The SVG
+version is used by <a href="https://caniuse.com/#feat=link-icon-svg">newer browsers</a>.</li>
+<li><strong>fonts/fonts.css</strong> contains the definition of which fonts to load.
+Custom fonts can be included in the <code>fonts</code> directory.</li>
+</ul>
+<p>Generally, when you want to tweak the theme, you don't need to override all the
+files. If you only need changes in the stylesheet, there is no point in
+overriding all the other files. Because custom files take precedence over
+built-in ones, they will not get updated with new fixes / features.</p>
+<p><strong>Note:</strong> When you override a file, it is possible that you break some
+functionality. Therefore I recommend to use the file from the default theme as
+template and only add / modify what you need. You can copy the default theme
+into your source directory automatically by using <code>mdbook init --theme</code> and just
+remove the files you don't want to override.</p>
+<p><code>mdbook init --theme</code> will not create every file listed above.
+Some files, such as <code>head.hbs</code>, do not have built-in equivalents.
+Just create the file if you need it.</p>
+<p>If you completely replace all built-in themes, be sure to also set
+<a href="../configuration/renderers.html#html-renderer-options"><code>output.html.preferred-dark-theme</code></a> in the config, which defaults to the
+built-in <code>navy</code> theme.</p>

+<p>mdBook uses <a href="https://highlightjs.org">Highlight.js</a> with a custom theme
+for syntax highlighting.</p>
+<p>Automatic language detection has been turned off, so you will probably want to
+specify the programming language you use like this:</p>
+<pre><code class="language-markdown">```rust
+fn main() {
+    // Some code
+}
+```
+</code></pre>
+<h2 id="supported-languages"><a class="header" href="#supported-languages">Supported languages</a></h2>
+<p>These languages are supported by default, but you can add more by supplying
+your own <code>highlight.js</code> file:</p>
+<ul>
+<li>apache</li>
+<li>armasm</li>
+<li>bash</li>
+<li>c</li>
+<li>coffeescript</li>
+<li>cpp</li>
+<li>csharp</li>
+<li>css</li>
+<li>d</li>
+<li>diff</li>
+<li>go</li>
+<li>handlebars</li>
+<li>haskell</li>
+<li>http</li>
+<li>ini</li>
+<li>java</li>
+<li>javascript</li>
+<li>json</li>
+<li>julia</li>
+<li>kotlin</li>
+<li>less</li>
+<li>lua</li>
+<li>makefile</li>
+<li>markdown</li>
+<li>nginx</li>
+<li>nim</li>

+<li>swift</li>
+<li>typescript</li>
+<li>x86asm</li>
+<li>xml</li>
+<li>yaml</li>
+</ul>
+<h2 id="custom-theme"><a class="header" href="#custom-theme">Custom theme</a></h2>
+<p>Like the rest of the theme, the files used for syntax highlighting can be
+overridden with your own.</p>
+<ul>
+<li><em><strong>highlight.js</strong></em> normally you shouldn't have to overwrite this file, unless
+you want to use a more recent version.</li>
+<li><em><strong>highlight.css</strong></em> theme used by highlight.js for syntax highlighting.</li>
+</ul>
+<p>If you want to use another theme for <code>highlight.js</code> download it from their
+website, or make it yourself, rename it to <code>highlight.css</code> and put it in
+the <code>theme</code> folder of your book.</p>
+<p>Now your theme will be used instead of the default theme.</p>
+<h2 id="improve-default-theme"><a class="header" href="#improve-default-theme">Improve default theme</a></h2>
+<p>If you think the default theme doesn't look quite right for a specific language,
+or could be improved, feel free to <a href="https://github.com/rust-lang/mdBook/issues">submit a new
+issue</a> explaining what you
+have in mind and I will take a look at it.</p>
+<p>You could also create a pull-request with the proposed improvements.</p>
+<p>Overall the theme should be light and sober, without too many flashy colors.</p>

+<p>Once you have the <code>mdbook</code> CLI tool installed, you can use it to create and render a book.</p>
+<h2 id="initializing-a-book"><a class="header" href="#initializing-a-book">Initializing a book</a></h2>
+<p>The <code>mdbook init</code> command will create a new directory containing an empty book for you to get started.
+Give it the name of the directory that you want to create:</p>
+<pre><code class="language-sh">mdbook init my-first-book
+</code></pre>
+<p>It will ask a few questions before generating the book.
+After answering the questions, you can change the current directory into the new book:</p>
+<pre><code class="language-sh">cd my-first-book
+</code></pre>
+<p>There are several ways to render a book, but one of the easiest methods is to use the <code>serve</code> command, which will build your book and start a local webserver:</p>
+<pre><code class="language-sh">mdbook serve --open
+</code></pre>
+<p>The <code>--open</code> option will open your default web browser to view your new book.
+You can leave the server running even while you edit the content of the book, and <code>mdbook</code> will automatically rebuild the output <em>and</em> automatically refresh your web browser.</p>
+<p>Check out the <a href="../cli/index.html">CLI Guide</a> for more information about other <code>mdbook</code> commands and CLI options.</p>
+<h2 id="anatomy-of-a-book"><a class="header" href="#anatomy-of-a-book">Anatomy of a book</a></h2>
+<p>A book is built from several files which define the settings and layout of the book.</p>
+<h3 id="booktoml"><a class="header" href="#booktoml"><code>book.toml</code></a></h3>
+<p>In the root of your book, there is a <code>book.toml</code> file which contains settings for describing how to build your book.
+This is written in the <a href="https://toml.io/">TOML markup language</a>.
+The default settings are usually good enough to get you started.
+When you are interested in exploring more features and options that mdBook provides, check out the <a href="../format/configuration/index.html">Configuration chapter</a> for more details.</p>
+<p>A very basic <code>book.toml</code> can be as simple as this:</p>
+<pre><code class="language-toml">[book]
+title = "My First Book"
+</code></pre>
+<h3 id="summarymd"><a class="header" href="#summarymd"><code>SUMMARY.md</code></a></h3>
+<p>The next major part of a book is the summary file located at <code>src/SUMMARY.md</code>.
+This file contains a list of all the chapters in the book.
+Before a chapter can be viewed, it must be added to this list.</p>
+<p>Here's a basic summary file with a few chapters:</p>
+<pre><code class="language-md"># Summary
+
+[Introduction](README.md)
+
+- [My First Chapter](my-first-chapter.md)
+- [Nested example](nested/README.md)
+    - [Sub-chapter](nested/sub-chapter.md)
+</code></pre>
+<p>Try opening up <code>src/SUMMARY.md</code> in your editor and adding a few chapters.
+If any of the chapter files do not exist, <code>mdbook</code> will automatically create them for you.</p>
+<p>For more details on other formatting options for the summary file, check out the <a href="../format/summary.html">Summary chapter</a>.</p>
+<h3 id="source-files"><a class="header" href="#source-files">Source files</a></h3>
+<p>The content of your book is all contained in the <code>src</code> directory.
+Each chapter is a separate Markdown file.
+Typically, each chapter starts with a level 1 heading with the title of the chapter.</p>
+<pre><code class="language-md"># My First Chapter
+
+Fill out your content here.
+</code></pre>
+<p>The precise layout of the files is up to you.
+The organization of the files will correspond to the HTML files generated, so keep in mind that the file layout is part of the URL of each chapter.</p>
+<p>While the <code>mdbook serve</code> command is running, you can open any of the chapter files and start editing them.
+Each time you save the file, <code>mdbook</code> will rebuild the book and refresh your web browser.</p>
+<p>Check out the <a href="../format/markdown.html">Markdown chapter</a> for more information on formatting the content of your chapters.</p>
+<p>All other files in the <code>src</code> directory will be included in the output.
+So if you have images or other static files, just include them somewhere in the <code>src</code> directory.</p>
+<h2 id="publishing-a-book"><a class="header" href="#publishing-a-book">Publishing a book</a></h2>
+<p>Once you've written your book, you may want to host it somewhere for others to view.
+The first step is to build the output of the book.
+This can be done with the <code>mdbook build</code> command in the same directory where the <code>book.toml</code> file is located:</p>
+<pre><code class="language-sh">mdbook build
+</code></pre>
+<p>This will generate a directory named <code>book</code> which contains the HTML content of your book.
+You can then place this directory on any web server to host it.</p>
+<p>For more information about publishing and deploying, check out the <a href="../continuous-integration.html">Continuous Integration chapter</a> for more.</p>

+<p>There are multiple ways to install the mdBook CLI tool.
+Choose any one of the methods below that best suit your needs.
+If you are installing mdBook for automatic deployment, check out the <a href="../continuous-integration.html">continuous integration</a> chapter for more examples on how to install.</p>
+<h2 id="pre-compiled-binaries"><a class="header" href="#pre-compiled-binaries">Pre-compiled binaries</a></h2>
+<p>Executable binaries are available for download on the <a href="https://github.com/rust-lang/mdBook/releases">GitHub Releases page</a>.
+Download the binary for your platform (Windows, macOS, or Linux) and extract the archive.
+The archive contains an <code>mdbook</code> executable which you can run to build your books.</p>
+<p>To make it easier to run, put the path to the binary into your <code>PATH</code>.</p>
+<h2 id="build-from-source-using-rust"><a class="header" href="#build-from-source-using-rust">Build from source using Rust</a></h2>
+<p>To build the <code>mdbook</code> executable from source, you will first need to install Rust and Cargo.
+Follow the instructions on the <a href="https://www.rust-lang.org/tools/install">Rust installation page</a>.
+mdBook currently requires at least Rust version 1.71.</p>
+<p>Once you have installed Rust, the following command can be used to build and install mdBook:</p>
+<pre><code class="language-sh">cargo install mdbook
+</code></pre>
+<p>This will automatically download mdBook from <a href="https://crates.io/">crates.io</a>, build it, and install it in Cargo's global binary directory (<code>~/.cargo/bin/</code> by default).</p>
+<p>To uninstall, run the command <code>cargo uninstall mdbook</code>.</p>
+<h3 id="installing-the-latest-master-version"><a class="header" href="#installing-the-latest-master-version">Installing the latest master version</a></h3>
+<p>The version published to crates.io will ever so slightly be behind the version hosted on GitHub.
+If you need the latest version you can build the git version of mdBook yourself.
+Cargo makes this <em><strong>super easy</strong></em>!</p>
+<pre><code class="language-sh">cargo install --git https://github.com/rust-lang/mdBook.git mdbook
+</code></pre>
+<p>Again, make sure to add the Cargo bin directory to your <code>PATH</code>.</p>
+<p>If you are interested in making modifications to mdBook itself, check out the <a href="https://github.com/rust-lang/mdBook/blob/master/CONTRIBUTING.md">Contributing Guide</a> for more information.</p>

+<p>This chapter gives an introduction on how to interact with a book produced by mdBook.
+This assumes you are reading an HTML book.
+The options and formatting will be different for other output formats such as PDF.</p>
+<p>A book is organized into <em>chapters</em>.
+Each chapter is a separate page.
+Chapters can be nested into a hierarchy of sub-chapters.
+Typically, each chapter will be organized into a series of <em>headings</em> to subdivide a chapter.</p>
+<h2 id="navigation"><a class="header" href="#navigation">Navigation</a></h2>
+<p>There are several methods for navigating through the chapters of a book.</p>
+<p>The <strong>sidebar</strong> on the left provides a list of all chapters.
+Clicking on any of the chapter titles will load that page.</p>
+<p>The sidebar may not automatically appear if the window is too narrow, particularly on mobile displays.
+In that situation, the menu icon (three horizontal bars) at the top-left of the page can be pressed to open and close the sidebar.</p>
+<p>The <strong>arrow buttons</strong> at the bottom of the page can be used to navigate to the previous or the next chapter.</p>
+<p>The <strong>left and right arrow keys</strong> on the keyboard can be used to navigate to the previous or the next chapter.</p>
+<h2 id="top-menu-bar"><a class="header" href="#top-menu-bar">Top menu bar</a></h2>
+<p>The menu bar at the top of the page provides some icons for interacting with the book.
+The icons displayed will depend on the settings of how the book was generated.</p>
+<div class="table-wrapper"><table><thead><tr><th>Icon</th><th>Description</th></tr></thead><tbody>
+<tr><td><i class="fa fa-bars"></i></td><td>Opens and closes the chapter listing sidebar.</td></tr>
+<tr><td><i class="fa fa-paint-brush"></i></td><td>Opens a picker to choose a different color theme.</td></tr>
+<tr><td><i class="fa fa-search"></i></td><td>Opens a search bar for searching within the book.</td></tr>
+<tr><td><i class="fa fa-print"></i></td><td>Instructs the web browser to print the entire book.</td></tr>
+<tr><td><i class="fa fa-github"></i></td><td>Opens a link to the website that hosts the source code of the book.</td></tr>
+<tr><td><i class="fa fa-edit"></i></td><td>Opens a page to directly edit the source of the page you are currently reading.</td></tr>
+</tbody></table>
+</div>
+<p>Tapping the menu bar will scroll the page to the top.</p>
+<h2 id="search"><a class="header" href="#search">Search</a></h2>
+<p>Each book has a built-in search system.
+Pressing the search icon (<i class="fa fa-search"></i>) in the menu bar, or pressing the <code>S</code> key on the keyboard will open an input box for entering search terms.
+Typing some terms will show matching chapters and sections in real time.</p>
+<p>Clicking any of the results will jump to that section.
+The up and down arrow keys can be used to navigate the results, and enter will open the highlighted section.</p>
+<p>After loading a search result, the matching search terms will be highlighted in the text.
+Clicking a highlighted word or pressing the <code>Esc</code> key will remove the highlighting.</p>
+<h2 id="code-blocks"><a class="header" href="#code-blocks">Code blocks</a></h2>
+<p>mdBook books are often used for programming projects, and thus support highlighting code blocks and samples.
+Code blocks may contain several different icons for interacting with them:</p>
+<div class="table-wrapper"><table><thead><tr><th>Icon</th><th>Description</th></tr></thead><tbody>
+<tr><td><i class="fa fa-copy"></i></td><td>Copies the code block into your local clipboard, to allow pasting into another application.</td></tr>
+<tr><td><i class="fa fa-play"></i></td><td>For Rust code examples, this will execute the sample code and display the compiler output just below the example (see <a href="../format/mdbook.html#rust-playground">playground</a>).</td></tr>
+<tr><td><i class="fa fa-eye"></i></td><td>For Rust code examples, this will toggle visibility of "hidden" lines. Sometimes, larger examples will hide lines which are not particularly relevant to what is being illustrated (see <a href="../format/mdbook.html#hiding-code-lines">hiding code lines</a>).</td></tr>
+<tr><td><i class="fa fa-history"></i></td><td>For <a href="../format/theme/editor.html">editable code examples</a>, this will undo any changes you have made.</td></tr>
+</tbody></table>
+</div>
+<p>Here's an example:</p>
+<pre><pre class="playground"><code class="language-rust edition2018"><span class="boring">#![allow(unused)]

-# Introduction
-
-**mdBook** is a command line tool to create books with Markdown.
-It is ideal for creating product or API documentation, tutorials, course materials or anything that requires a clean,
-easily navigable and customizable presentation.
-
-* Lightweight [Markdown] syntax helps you focus more on your content
-* Integrated [search] support
-* Color [syntax highlighting] for code blocks for many different languages
-* [Theme] files allow customizing the formatting of the output
-* [Preprocessors] can provide extensions for custom syntax and modifying content
-* [Backends] can render the output to multiple formats
-* Written in [Rust] for speed, safety, and simplicity
-* Automated testing of [Rust code samples]
-
-This guide is an example of what mdBook produces.
-mdBook is used by the Rust programming language project, and [The Rust Programming Language][trpl] book is another fine example of mdBook in action.

-# Command Line Tool
-
-The `mdbook` command-line tool is used to create and build books.
-After you have [installed](../guide/installation.md) `mdbook`, you can run the `mdbook help` command in your terminal to view the available commands.
-
-This following sections provide in-depth information on the different commands available.
-
-* [`mdbook init <directory>`](init.md) — Creates a new book with minimal boilerplate to start with.
-* [`mdbook build`](build.md) — Renders the book.
-* [`mdbook watch`](watch.md) — Rebuilds the book any time a source file changes.
-* [`mdbook serve`](serve.md) — Runs a web server to view the book, and rebuilds on changes.
-* [`mdbook test`](test.md) — Tests Rust code samples.
-* [`mdbook clean`](clean.md) — Deletes the rendered output.
-* [`mdbook completions`](completions.md) — Support for shell auto-completion.

-# The build command
-
-The build command is used to render your book:
-
-```bash
-mdbook build
-```
-
-It will try to parse your `SUMMARY.md` file to understand the structure of your
-book and fetch the corresponding files. Note that this will also create files
-mentioned in `SUMMARY.md` which are not yet present.
-
-The rendered output will maintain the same directory structure as the source for
-convenience. Large books will therefore remain structured when rendered.
-
-#### Specify a directory
-
-The `build` command can take a directory as an argument to use as the book's
-root instead of the current working directory.
-
-```bash
-mdbook build path/to/book
-```
-
-#### --open
-
-When you use the `--open` (`-o`) flag, mdbook will open the rendered book in
-your default web browser after building it.
-
-#### --dest-dir
-
-The `--dest-dir` (`-d`) option allows you to change the output directory for the
-book. Relative paths are interpreted relative to the book's root directory. If
-not specified it will default to the value of the `build.build-dir` key in
-`book.toml`, or to `./book`.

-# The completions command
-
-The completions command is used to generate auto-completions for some common shells.
-This means when you type `mdbook` in your shell, you can then press your shell's auto-complete key (usually the Tab key) and it may display what the valid options are, or finish partial input.
-
-The completions first need to be installed for your shell:

-# The init command
-
-There is some minimal boilerplate that is the same for every new book. It's for
-this purpose that mdBook includes an `init` command.
-
-The `init` command is used like this:
-
-```bash
-mdbook init
-```
-
-When using the `init` command for the first time, a couple of files will be set
-up for you:
-```bash
-book-test/

-└── src
-    ├── chapter_1.md
-    └── SUMMARY.md
-```
-
-- The `src` directory is where you write your book in markdown. It contains all
-  the source files, configuration files, etc.
-
-- The `book` directory is where your book is rendered. All the output is ready
-  to be uploaded to a server to be seen by your audience.
-
-- The `SUMMARY.md` is the skeleton of your
-  book, and is discussed in more detail [in another
-  chapter](../format/summary.md).
-
-#### Tip: Generate chapters from SUMMARY.md
-
-When a `SUMMARY.md` file already exists, the `init` command will first parse it
-and generate the missing files according to the paths used in the `SUMMARY.md`.
-This allows you to think and create the whole structure of your book and then
-let mdBook generate it for you.
-
-#### Specify a directory
-
-The `init` command can take a directory as an argument to use as the book's root
-instead of the current working directory.
-
-```bash
-mdbook init path/to/book
-```
-
-#### --theme
-
-When you use the `--theme` flag, the default theme will be copied into a
-directory called `theme` in your source directory so that you can modify it.
-
-The theme is selectively overwritten, this means that if you don't want to
-overwrite a specific file, just delete it and the default file will be used.
-
-#### --title
-
-Specify a title for the book. If not supplied, an interactive prompt will ask for 
-a title. 
-
-```bash
-mdbook init --title="my amazing book"

-# The test command
-
-When writing a book, you sometimes need to automate some tests. For example,
-[The Rust Programming Book](https://doc.rust-lang.org/stable/book/) uses a lot
-of code examples that could get outdated. Therefore it is very important for
-them to be able to automatically test these code examples.
-
-mdBook supports a `test` command that will run all available tests in a book. At
-the moment, only Rust tests are supported.
-
-#### Disable tests on a code block
-
-rustdoc doesn't test code blocks which contain the `ignore` attribute:
-
-    ```rust,ignore
-    fn main() {}
-    ```
-
-rustdoc also doesn't test code blocks which specify a language other than Rust:
-
-    ```markdown
-    **Foo**: _bar_
-    ```
-
-rustdoc *does* test code blocks which have no language specified:
-
-    ```
-    This is going to cause an error!
-    ```
-
-#### Specify a directory
-
-The `test` command can take a directory as an argument to use as the book's root
-instead of the current working directory.
-
-```bash
-mdbook test path/to/book

-
-#### --library-path
-
-The `--library-path` (`-L`) option allows you to add directories to the library
-search path used by `rustdoc` when it builds and tests the examples. Multiple
-directories can be specified with multiple options (`-L foo -L bar`) or with a
-comma-delimited list (`-L foo,bar`). The path should point to the Cargo
-[build cache](https://doc.rust-lang.org/cargo/guide/build-cache.html) `deps` directory that
-contains the build output of your project. For example, if your Rust project's book is in a directory
-named `my-book`, the following command would include the crate's dependencies when running `test`:
-
-```shell
-mdbook test my-book -L target/debug/deps/
-```
-
-See the `rustdoc` command-line [documentation](https://doc.rust-lang.org/rustdoc/command-line-arguments.html#-l--library-path-where-to-look-for-dependencies)
-for more information.

-# Running `mdbook` in Continuous Integration
-
-There are a variety of services such as [GitHub Actions] or [GitLab CI/CD] which can be used to test and deploy your book automatically.
-
-The following provides some general guidelines on how to configure your service to run mdBook.
-Specific recipes can be found at the [Automated Deployment] wiki page.
-
-[GitHub Actions]: https://docs.github.com/en/actions
-[GitLab CI/CD]: https://docs.gitlab.com/ee/ci/
-[Automated Deployment]: https://github.com/rust-lang/mdBook/wiki/Automated-Deployment
-
-## Installing mdBook
-
-There are several different strategies for installing mdBook.
-The particular method depends on your needs and preferences.
-
-### Pre-compiled binaries
-
-Perhaps the easiest method is to use the pre-compiled binaries found on the [GitHub Releases page][releases].
-A simple approach would be to use the popular `curl` CLI tool to download the executable:
-
-```sh
-mkdir bin
-curl -sSL https://github.com/rust-lang/mdBook/releases/download/v0.4.37/mdbook-v0.4.37-x86_64-unknown-linux-gnu.tar.gz | tar -xz --directory=bin
-bin/mdbook build
-```
-
-Some considerations for this approach:
-
-* This is relatively fast, and does not necessarily require dealing with caching.
-* This does not require installing Rust.
-* Specifying a specific URL means you have to manually update your script to get a new version.
-  This may be a benefit if you want to lock to a specific version.
-  However, some users prefer to automatically get a newer version when they are published.
-* You are reliant on the GitHub CDN being available.
-
-[releases]: https://github.com/rust-lang/mdBook/releases
-
-### Building from source
-
-Building from source will require having Rust installed.
-Some services have Rust pre-installed, but if your service does not, you will need to add a step to install it.
-
-After Rust is installed, `cargo install` can be used to build and install mdBook.
-We recommend using a SemVer version specifier so that you get the latest **non-breaking** version of mdBook.
-For example:
-
-```sh
-cargo install mdbook --no-default-features --features search --vers "^0.4" --locked
-```
-
-This includes several recommended options:
-
-* `--no-default-features` — Disables features like the HTTP server used by `mdbook serve` that is likely not needed on CI.
-  This will speed up the build time significantly.
-* `--features search` — Disabling default features means you should then manually enable features that you want, such as the built-in [search] capability.
-* `--vers "^0.4"` — This will install the most recent version of the `0.4` series.
-  However, versions after like `0.5.0` won't be installed, as they may break your build.
-  Cargo will automatically upgrade mdBook if you have an older version already installed.
-* `--locked` — This will use the dependencies that were used when mdBook was released.
-  Without `--locked`, it will use the latest version of all dependencies, which may include some fixes since the last release, but may also (rarely) cause build problems.
-
-You will likely want to investigate caching options, as building mdBook can be somewhat slow.
-
-[search]: guide/reading.md#search
-
-## Running tests
-
-You may want to run tests using [`mdbook test`] every time you push a change or create a pull request.
-This can be used to validate Rust code examples in the book.
-
-This will require having Rust installed.
-Some services have Rust pre-installed, but if your service does not, you will need to add a step to install it.
-
-Other than making sure the appropriate version of Rust is installed, there's not much more than just running `mdbook test` from the book directory.
-
-You may also want to consider running other kinds of tests, like [mdbook-linkcheck] which will check for broken links.
-Or if you have your own style checks, spell checker, or any other tests it might be good to run them in CI.
-
-[`mdbook test`]: cli/test.md
-[mdbook-linkcheck]: https://github.com/Michael-F-Bryan/mdbook-linkcheck#continuous-integration
-
-## Deploying
-
-You may want to automatically deploy your book.
-Some may want to do this every time a change is pushed, and others may want to only deploy when a specific release is tagged.
-
-You'll also need to understand the specifics on how to push a change to your web service.
-For example, [GitHub Pages] just requires committing the output onto a specific git branch.
-Other services may require using something like SSH to connect to a remote server.
-
-The basic outline is that you need to run `mdbook build` to generate the output, and then transfer the files (which are in the `book` directory) to the correct location.
-
-You may then want to consider if you need to invalidate any caches on your web service.
-
-See the [Automated Deployment] wiki page for examples of various different services.
-
-[GitHub Pages]: https://docs.github.com/en/pages
-
-### 404 handling
-
-mdBook automatically generates a 404 page to be used for broken links.
-The default output is a file named `404.html` at the root of the book.
-Some services like [GitHub Pages] will automatically use this page for broken links.
-For other services, you may want to consider configuring the web server to use this page as it will provide the reader navigation to get back to the book.
-
-If your book is not deployed at the root of the domain, then you should set the [`output.html.site-url`] setting so that the 404 page works correctly.
-It needs to know where the book is deployed in order to load the static files (like CSS) correctly.
-For example, this guide is deployed at <https://rust-lang.github.io/mdBook/>, and the `site-url` setting is configured like this:
-
-```toml
-# book.toml
-[output.html]
-site-url = "/mdBook/"
-```
-
-You can customize the look of the 404 page by creating a file named `src/404.md` in your book.
-If you want to use a different filename, you can set [`output.html.input-404`] to a different filename.

-# For Developers
-
-While `mdbook` is mainly used as a command line tool, you can also import the
-underlying library directly and use that to manage a book. It also has a fairly
-flexible plugin mechanism, allowing you to create your own custom tooling and
-consumers (often referred to as *backends*) if you need to do some analysis of
-the book or render it in a different format.
-
-The *For Developers* chapters are here to show you the more advanced usage of
-`mdbook`.
-
-The two main ways a developer can hook into the book's build process is via,
-
-- [Preprocessors](preprocessors.md)
-- [Alternative Backends](backends.md)
-
-
-## The Build Process
-
-The process of rendering a book project goes through several steps.
-
-1. Load the book
-    - Parse the `book.toml`, falling back to the default `Config` if it doesn't
-       exist
-    - Load the book chapters into memory
-    - Discover which preprocessors/backends should be used
-2. For each backend:
-   1. Run all the preprocessors.
-   2. Call the backend to render the processed result.
-
-
-## Using `mdbook` as a Library
-
-The `mdbook` binary is just a wrapper around the `mdbook` crate, exposing its
-functionality as a command-line program. As such it is quite easy to create your
-own programs which use `mdbook` internally, adding your own functionality (e.g.
-a custom preprocessor) or tweaking the build process.
-
-The easiest way to find out how to use the `mdbook` crate is by looking at the
-[API Docs]. The top level documentation explains how one would use the
-[`MDBook`] type to load and build a book, while the [config] module gives a good
-explanation on the configuration system.
-
-
-[`MDBook`]: https://docs.rs/mdbook/*/mdbook/book/struct.MDBook.html
