Prerequisites

1. Install Rails

First, you must have a working version of Rails. Depending on your operating system, there is a different guide to follow:

2. Download a Text Editor (if required)

You will also need a text editor in which to write your code. If you already have one installed, feel free to skip this step. We use Sublime Text.
