title: How do I configure config.yml so that I can install devkit?
body: <pre><code>Microsoft Windows [Version 6.1.7601]

  C:\Users\Aaron&gt;cd /DevKit
  The system cannot find the path specified.
  
  C:\Users\Aaron&gt;cd \DevKit
  
  C:\DevKit&gt;ruby dk.rb init
  
  Initialization complete! Please review and modify the auto-generated
  'config.yml' file to ensure it contains the root directories to all
  of the installed Rubies you want enhanced by the DevKit.
  
  C:\DevKit&gt;ruby dk.rb install --force
  Invalid configuration or no Rubies listed. Please fix 'config.yml'
  and rerun 'ruby dk.rb install'
  
  C:\DevKit&gt;
  </code></pre>
  
  <p>The config.yml looks like this:</p>
  
  <pre><code># This configuration file contains the absolute path locations of all
  # installed Rubies to be enhanced to work with the DevKit. This config
  # file is generated by the 'ruby dk.rb init' step and may be modified
  # before running the 'ruby dk.rb install' step. To include any installed
  # Rubies that were not automagically discovered, simply add a line below
  # the triple hyphens with the absolute path to the Ruby root directory.
  #
  # Example:
  #
  # ---
  # - C:/ruby19trunk
  # - C:/ruby192dev
  #
  --- 
  </code></pre>
  
  <p>I am completely stumped I have no clue what to do. Can someone tell me how to resolve this problem?</p>
