This is online html book for Ruby on Windows. I wish I had read it sooner. It’s also useful for Shoes folks that want to up their game and learn a more about Ruby on Windows. The description of RubyInstaller and Devkit answered several question and do believe I can fix a Shoes bug with the info. I didn’t read the Rails stuff so I can’t comment on that.
I also like the Atom text editor for OSX and Windows. I’m not ready to give up on Geany on Linux yet, but I could.
