title: How do I fetch a branch on someone else's fork on GitHub?
body: <p>I've forked from a repo on GitHub. I want to get the code from a branch on another user's fork.  </p>
  
  <p>Must I clone this user's whole repo to a separate local repo or can I do something like <code>git checkout link_to_the_other_users_branch</code>?</p>
