 dotty
 =====
 
-The experimental compiler for a Scala dialect based on DOT
+The experimental compiler for a Scala dialect based on DOT.
+
+### To get started:
+```
+  sbt compile
+  sbt run
+  sbt test
+```
+At least half of the tests fail, we need to diagnose them.
+
+
+### To use the Scala IDE:
+```
+  sbt eclipse
+```
+Notes: 
+ * You will need the Scala IDE for 2.11.0-M7
+ * There are 2 spurious version incompatibility warnings
+ * To run dotty in Eclipse:
+   * Navigate to `dotty.tools.dotc.Main`
+   * `Run As...` > `Scala Application`
+   * then go to `Run Configurations` > `Main$` > `Classpath` > `Bootstrap entries`:
+     * add the Scala library (`Advanced...` > `Add library...` > `Scala library`)
+     * add the dotty classfiles (`Add projects...` > `[x] dotty`)
+   * then go to `Run Configurations` > `Main$` > `Arguments` and add `${project_loc}/examples/hello.scala`
