+This is your new Play application
+=================================
+
+This file will be packaged with your application when using `activator dist`.
+
+There are several demonstration files available in this template.
+
+Controllers
+===========
+
+- HomeController.scala:
+
+  Shows how to handle simple HTTP requests.
+
+- AsyncController.scala:
+
+  Shows how to do asynchronous programming when handling a request.
+
+- CountController.scala:
+
+  Shows how to inject a component into a controller and use the component when
+  handling requests.
+
+Components
+==========
+
+- Module.scala:
+
+  Shows how to use Guice to bind all the components needed by your application.
+
+- Counter.scala:
+
+  An example of a component that contains state, in this case a simple counter.
+
+- ApplicationTimer.scala:
+
+  An example of a component that starts when the application starts and stops
+  when the application stops.
+
+Filters
+=======
+
+- Filters.scala:
+
+  Creates the list of HTTP filters used by your application.
+
+- ExampleFilter.scala
+
+  A simple filter that adds a header to every response.
