It just takes a few steps to get started with Ruby and Rails. Find the section for your platform below:

Download and Install Apple’s XCode from http://developer.apple.com/technology/Xcode.html. XCode is Apple’s development platform and it includes all the compilers and tools you’ll need to get started with multiple languages including Ruby.
Enter Terminal and issue the following commands:
- ruby -v
  If you have OS X 10.5 or later then Ruby is already installed on your system. This command should show you exactly what version. Anything above 1.8.5 should be fine for our purposes.
- sudo gem update --system
  This command will update the gem package management system to the latest version
- sudo gem install fastercsv twitter hpricot rails sunlight
