 ## Prerequisites ##
 
 Before we begin, we first need to install the command line tool that will be used to upload and manage your application. Cloud Foundry uses a tool called [**cf**](https://github.com/cloudfoundry/cf). This tool is written in Ruby, so you must have Ruby installed. If you are running on Windows, you can install Ruby from [this](http://rubyinstaller.org/downloads/) website.
