title: how do I make an existing branch track a remote branch
body: <p>For almost a year, I have simply been copying the zip file anytime new changes were made to avoid dealing with <code>git pull fetch track origin rebase master slave</code>.</p>
  <p>How hard can it possibly be to simply download or clone a repository, and then set it to track changes?<br />
  And, while you are at it, don't overwrite my changes.<br />
  I am not a developer, so have no need to push(upload).</p>
  <p>Are you able to track an HTTPS address or does it have to be SSSH?</p>
  <p>I simply want to track changes on <a href="https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x" rel="nofollow noreferrer">https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x</a><br />
  That's it.</p>
