how to use ruby mine

i installed ruby mine 3.0.1 version., installed gems cucumber need to use cucumber and ruby with rubymine can u guide me for that thanks sri

Rubymine has its own mailing list: http://devnet.jetbrains.net/community/ruby

And the newest version is 3.1, so the first thing I'd do is get the latest version and try with that.

Better to use latest RubyMine 3.1.1 RC2 build. 3.1.1 version is a bug fix update for 3.1.
