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

Rubymine has its own mailing list:

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.
