title: What does this GIT command do?
body: <p>I'm trying to understand what this GIT command does:</p>
  
  <p><code>git push origin master:release_candidate --force</code></p>
  
  <p>I know <code>git push origin master</code> pushes the local master to the remote origin. </p>
  
  <p>I would like to know the <code>:release_candidate --force</code> part.</p>
