So confused of this library due to slow support and no documentation/not even class definition in package 😞

Calm down, the library is supported only by me (at the moment) and it's open-source project to which I invest my free time. You can help by providing PR with a functions documentation and help other people instead of blaming to someone. We (at JetBrains) are going to improve site and code documentation but it will take time.

Ok, ill try to document that in next few days, will contact if found problems :)
