+## Building
+
+To build the module, use Maven's `package` goal:
+
+```
+mvn clean package
+```
+
+The `war` file will be available at `target/deep-jsf.war`
+
+## Running
+
+The `war` application is deployed to a Java EE 7 compliant application server, for example, to GlassFish 4 or later.
+
+The example then will be accessible at http://localhost:8080/deep-jsf/index.xhtml
