+## Installing Ruby
+
+Before you begin, you must have Ruby installed on your machine. There are a couple of different ways you can get ruby setup.
+
+- [Download from ruby-lang.org](https://www.ruby-lang.org/en/downloads/)
+- Setup using [RVM][1] or [rbenv][2]
+
+We recommend using a version manager (you are only able to do that if you are on a UNIX based system like OS X or Linux), so that you can manage diffrent Ruby versions.
+
+Alternatively, if you are having trouble you can create an account on [nitrous.io](https://www.nitrous.io) which gives you a ready environment that you can use in the browser.
+
+## Ruby in 100 minutes
