To get everything configured, please install the following:
+ Ruby Installer for Windows http://rubyinstaller.org/
+ Git for Windows (which, importantly, includes Git Bash): https://git-for-windows.github.io/
We recommend making a shortcut to Git Bash in a convenient place.
+ GitHub Desktop https://desktop.github.com/
+ You'll need to create a free GitHub account in order to use it: https://github.com
You don't strictly need GitHub Desktop, but you may find that it's the easiest way to use GitHub on Windows.
+ Heroku Toolbelt: https://toolbelt.heroku.com/
You'll also need a free Heroku account to use this.
Then do `gem install rails`. We prefer to use the Ruby installer, and then manually install rails, over using the Rails Installer.
