title: Why is git push gerrit HEAD:refs/for/master used instead of git push origin master
body: <p>I've just started using gerrit and I want to know why we need to do <code>git push gerrit HEAD:refs/for/master</code> instead of doing <code>git push origin master</code></p>
  
  <p>If I do <code>git push origin master</code> I get the error saying <code>! [remote rejected] master -&gt; master (prohibited by Gerrit)</code></p>
