configuring ruby for emacs on Windows

I am trying to build a project on ruby, u开发者_开发问答sing Emacs for editor. I can see that the ruby mode is activated when I create a .rb file, but I would like to be eable to evaluate the code interactively (a bit like C-x C-e with Emacs Lisp). Is there a way to plug irb inside emacs for that?

Many thanks!
