title: How to set up a git project to use an external repo submodule?
body: <p>I'd like to create a repo which pulls in a remote repo.</p>
  
  <p>For example, let's say jQuery as a submodule:</p>
  
  <pre><code>git://github.com/jquery/jquery.git
  </code></pre>
  
  <p>What would be the process of creating a repo with jQuery as a submodule and adding my own external as a remote repo.</p>
  
  <p>Also once this is setup, if I push / pull to my own remote, will the external remain intact?</p>
