+  This is documentation for the Phoenix project.
+
+  By default, Phoenix applications depend on other packages besides
+  Phoenix itself. Below we provide a short explanation with links to
+  their documentation for each of those projects:
+
+    * [Ecto](http://hexdocs.pm/ecto) - a language integrated query and
+      database wrapper
+
+    * [Phoenix](http://hexdocs.pm/phoenix) - the Phoenix web framework
+      (these docs)
+
+    * [Phoenix HTML](http://hexdocs.pm/phoenix_html) - conveniences for
+      working with HTML in Phoenix
+
+    * [Plug](http://hexdocs.pm/plug) - a specification and conveniences
+      for composable modules in between web applications
+
+  There are also optional packages depending on your configuration:
+
+    * [Phoenix PubSub Redis](http://hexdocs.pm/phoenix_live_reload) - use
+      Redis to power Phoenix PubSub system
