+## Working with the project in IDEA
+
+The [root kotlin project](https://github.com/JetBrains/kotlin) already has an IDEA project, you can just open it in IDEA.
+
+**Note** though that you need a recent IDEA build (e.g. 11 EAP) which should **not** contain the Kotlin plugin!
+
+From this root project there are Run/Debug Configurations for running IDEA or the Compiler Tests for example; so if you want to try out the latest greatest IDEA plugin
+
+* VCS -> Git -> Pull
+* Run IDEA
+* a child IDEA with the Kotlin plugin will then startup
+* you can now open the [kotlin libraries project](https://github.com/JetBrains/kotlin/libraries) to then work with the various kotlin libraries etc.
+
+### Using a pre-built Kotlin IDEA plugin
+
+In a recent IDEA EAP build install the Kotlin plugin:
+
+Preferences -> Plugins -> Browse Repositories -> Manage Repositories... -> + to add a new repository URL
+
+ * [http://www.jetbrains.com/kotlin/eap-plugin-repository/updatePlugins.xml](http://www.jetbrains.com/kotlin/eap-plugin-repository/updatePlugins.xml)
+
+You can now open any Kotlin based projects. Its advisable you don't open the [root kotlin project](https://github.com/JetBrains/kotlin) as thats intended to be used to
+build the kotlin compiler and plugin itself; instead open the [kotlin libraries project](https://github.com/JetBrains/kotlin/libraries)
