title: Setting upstream to a submodule (or how to include a GitHub fork as a submodule)
body: <p>I'm quite new to this Git thing and need a little help.</p>
  
  <p>I recently created a new repo on GitHub and cloned it on my desktop. Let's call it <strong>myProject</strong>. I also have a fork in my GitHub account which I included in myProject as a submodule. Let's call this <strong>myForkOfOtherProject</strong>, which is a fork of <strong>otherProject</strong>.</p>
  
  <p>So, this is the current situation:</p>

  <p><a href="https://help.github.com/articles/fork-a-repo">According to GitHub</a>:</p>
  
  <blockquote>
    <p>When a repo is cloned, it has a default remote called <strong>origin</strong> that
    points to your fork on GitHub, not the original repo it was forked
    from. To keep track of the original repo, you need to add another
    remote named <strong>upstream</strong>.</p>
  </blockquote>
  
  <p>So, my question is, how do I set the upstream to the submodule? Or am I not understanding something?</p>
  
  <p>Thank you in advance.</p>
