+## Adding an SBT dependency
+To depend on scala-xml in SBT, add something like this to your build.sbt:
+
+```
+libraryDependencies += "org.scala-lang.modules" %% "scala-java8-compat" % "0.2.0"
+```
+
+Maven users, or sbt users looking to support multiple Scala versions, please see the more elaborate example in https://github.com/scala/scala-module-dependency-sample.
+
+The API is currently still experimental: we do not yet guarantee source or binary compatibility with future releases.

+## Future work
   - Converters for `java.util.function`, `java.util.stream`
   - [`Spliterator`](https://docs.oracle.com/javase/8/docs/api/java/util/Spliterator.html)s for Scala collections
