+
+pages:
+  stage: deploy
+  image: rust:alpine
+  variables:
+    CARGO_HOME: $CI_PROJECT_DIR/cargo
+  before_script:
+    - export PATH="$PATH:$CARGO_HOME/bin"
+    - mdbook --version || cargo install mdbook
+  script:
+        - mdbook build -d public
+  only:
+      - master 
+  artifacts:
+      paths:
+          - public
