 # Scala modules sbt plugin
 
-This is an sbt plugin for building Scala modules (scala-xml,
-scala-parser-combinators, and so on).
+This is an sbt plugin for building Scala modules.
 
-The major benefit of the plugin is to provide automated tag-based
-publishing.  A release is made by pushing a tag to GitHub.  Travis
-then stages artifacts on Sonatype.  Pressing "Close" and "Release" in
-the Sonatype web UI will then send the artifacts to Maven Central.
+## What modules use it?
+
+* [scala-async](https://github.com/scala/scala-async)
+* [scala-collection-compat](https://github.com/scala/scala-collection-compat)
+* [scala-java8-compat](https://github.com/scala/scala-java8-compat)
+* [scala-parallel-collections](https://github.com/scala/scala-parallel-collections)
+* [scala-parser-combinators](https://github.com/scala/scala-parser-combinators)
+* [scala-partest](https://github.com/scala/scala-partest)
+* [scala-swing](https://github.com/scala/scala-swing)
+* [scala-xml](https://github.com/scala/scala-xml)
+
+## Why this plugin?
+
+Having a shared plugin reduces duplication between the above
+repositories.  Reducing duplication makes maintenance easier and
+helps ensure consistency.
+
+A major feature of the plugin is automated tag-based publishing.  A
+release is made by pushing a tag to GitHub.  Travis-CI then stages
+artifacts on Sonatype.  Pressing "Close" and "Release" in the Sonatype
+web UI will then send the artifacts to Maven Central.
+
+## Branches and versions
+
+The main development branch is 2.x; only sbt 1 is supported there.
+
+sbt 0.13 support is on the legacy 1.x branch.
+
+Scala modules are encouraged to move to sbt 1 on their primary
+development branches as soon as reasonably possible.
 
 ## Usage
 
 Add the plugin to the `project/plugins.sbt` file:
 
 ```
-addSbtPlugin("org.scala-lang.modules" % "sbt-scala-module" % "1.0.14")
+addSbtPlugin("org.scala-lang.modules" % "sbt-scala-module" % "2.0.0")
 ```
