+Installing the Scala IDE Play2 plug-in
+--------------------------------------
+
+The `Scala IDE Play2 plug-in <https://github.com/scala-ide/scala-ide-play2>`_ provides
+first-class support for Play2 Route and Template files in Eclipse. In practice, what this
+means is that many of the features your are used to have in the Scala Editor (e.g.,
+syntax highlighting, errors-as-you-type reporting, code completion, hyperlinking) are also
+available when editing Play2 files.
+
+The Play2 plug-in can be installed via **the same Eclipse update-site that you used to install
+the Scala IDE**. The Play2 plug-in is listed under the *Scala IDE plugins* group.
