 ### Building for different versions of IntelliJ IDEA and Android Studio
 
-Kotlin plugin is intended to work with several recent versions of IntelliJ IDEA and Android Studio. Each platform is allowed to have a different set of features and might provide a slightly different API. Instead of using several parallel Git branches, project stores everything in a single branch, but files may have counterparts with version extensions (\*.as32, \*.172, \*.181). The primary file is expected to be replaced with its counterpart when targeting non-default platform.

+Currently only committers can assign issues to themselves so just add a comment if you're starting work on it.
+
+A nice gentle way to contribute would be to review the [standard library docs](https://kotlinlang.org/api/latest/jvm/stdlib/index.html)
+and find classes or functions which are not documented very well and submit a patch.
+
+In particular it'd be great if all functions included a nice example of how to use it such as for the
+[`hashMapOf()`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/hash-map-of.html) function.
+This is implemented using the [`@sample`](https://github.com/JetBrains/kotlin/blob/1.1.0/libraries/stdlib/src/kotlin/collections/Maps.kt#L91)
+macro to include code from a test function. The benefits of this approach are twofold; First, the API's documentation is improved via beneficial examples that help new users and second, the code coverage is increased.
+
+Also the [JavaScript translation](https://github.com/JetBrains/kotlin/blob/master/js/ReadMe.md) could really use your help. See the [JavaScript contribution section](https://github.com/JetBrains/kotlin/blob/master/js/ReadMe.md) for more details.
+
+Some of the code in the standard library is created by generating code from templates. See the [README](libraries/stdlib/ReadMe.md) in the stdlib section for how to run the code generator. The existing templates can be used as examples for creating new ones.
+
+## Submitting patches
+
+The best way to submit a patch is to [fork the project on github](https://help.github.com/articles/fork-a-repo/) then send us a
+[pull request](https://help.github.com/articles/creating-a-pull-request/) via [github](https://github.com).
+
+If you create your own fork, it might help to enable rebase by default
+when you pull by executing
+``` bash
+git config --global pull.rebase true
+```
+This will avoid your local repo having too many merge commits
+which will help keep your pull request simple and easy to apply.
