Getting Started with Ruby

Ruby was developed in the mid 90s by Yukihiro Matsumoto, it's an object orientated programming language desgined to be productive, enjoyable to write and make developers happy.

This guide is to help anyone who hasn't or just started writing their first Ruby code. I have added a few resources for beginners a few advanced topics once you're ready to move on.
