title: How do I work with a git repository within another repository?
body: <p>I have a Git media repository where I'm keeping all of my JavaScript and CSS master files and scripts that I'll use on various projects. </p>
  
  <p>If I create a new project that's in its own Git repository, how do I use JavaScript files from my media repository in my new project in a way that makes it so I don't have to update both copies of the script when I make changes? </p>
