+# Demo Book
+
+This is a simple demo book, which is intended to be used for verifying and validating style changes in mdBook.
+This contains dummy examples of various markdown elements and code languages, so that one can check changes made in mdBook styles.
+
+This rough outline is :
+
+- individual : contains basic markdown elements such as headings, paragraphs, links etc.
+- languages : contains a `hello world` in each of supported language to see changes in syntax highlighting
+- rust : contains language examples specific to rust, such as play pen, runnable examples etc.
+
+This is more for checking and fixing style, rather than verifying that correct code is generated for given markdown, that is better handled in tests.
