 We love contributions! There's [lots to do](http://youtrack.jetbrains.com/issues/KT) so why not chat
 with us on the [forum](http://devnet.jetbrains.net/community/kotlin?view=discussions) about what you're interested in doing?
 
+If you want to find some issues to start off with, try [this query](http://youtrack.jetbrains.com/issues/KT?q=-Resolved+%23Kontributor) which should find all issues that are not resolved assigned to Kontributor.
+Currently only committers can assign issues to themselves so just add a comment if you're starting work on it.
+
 The best way to contribute is to [fork the project on github](http://help.github.com/fork-a-repo/) then send us a
 [pull request](http://help.github.com/send-pull-requests/) via [github](http://github.com).
 
 If you create your own fork, it might help to [enable rebase by default when you pull](http://d.strelau.net/post/47338904/git-pull-rebase-by-default)
 which will avoid your local repo having too many merge commits which will help keep your pull request simple and easy to apply.
