+Docs is organized in several Maven modules:
+
+  - docs-parent
+  - docs-core
+  - docs-web
+  - docs-web-common
+
+First off, clone the repository: `git clone git://github.com/sismics/docs.git`
+or download the sources from GitHub.
+
+#### Launch the build
+
+From the `docs-parent` directory:
+
+    mvn clean -DskipTests install
+
+#### Run a stand-alone version
+
+From the `docs-web` directory:
+
+    mvn jetty:run
+
+#### Build a .war to deploy to your servlet container
+
+From the `docs-web` directory:
+
+    mvn -Pprod -DskipTests clean install
+
+You will get your deployable WAR in the `target` directory.
