In this first section, we're going to focus on environment configuration. We'll specifically walk through the process to setup your system to run Ruby and Rails based applications.

If you already have the Rails system setup, feel free to skim over these guides. It is recommended if you use a text editor such as sublime you view that guide. There is also a "deep dive" section on more advanced ways to use the command line.

If you don't have a Rails system setup, then go through each section. These guides have step-by-step instructions, including the exact commands to run, and the items you will need to install, for your programming environment. This includes Ruby and RVM, the postgres database, working with Git and all the everything you need to start building Rails Apps.
