A nice gentle way to contribute would be to review the [API docs](http://jetbrains.github.com/kotlin/versions/snapshot/apidocs/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 <a href="http://jetbrains.github.com/kotlin/versions/snapshot/apidocs/kotlin/java/util/Collection-extensions.html#filter(jet.Function1)">filter()</a> function on Collection. This is implemented using the <a href="https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/src/kotlin/JLangIterablesLazy.kt#L17">@includeFunctionBody</a> macro to include code from a test function. This serves as a double win; the API gets better documented with nice examples to help new users and the code gets more test coverage.
