What is the best place to start/ask if I would like to start contributing to kotlin? Are there any starter tasks or something besides the documentation?

There's a channel #kontributors, there's a page here https://kotlinlang.org/contribute.html and there are good starting issues tagged here: https://youtrack.jetbrains.com/issues/KT?q=%23Unresolved%20tag:%20%7BUp%20For%20Grabs%7D

Awesome, thank you!
