title: rejected master -> master (non-fast-forward)
body: <p>I'm trying to push my project (all files in a new repository). I follow the steps but when I push with <code>git push -u origin master</code> I get this error:</p>
  
  <pre><code>! [rejected]        master -&gt; master (non-fast-forward)
  error: failed to push some refs to 'git@github.com:asantoya/projectnewbies.git'
  To prevent you from losing history, non-fast-forward updates were rejected
  Merge the remote changes (e.g. 'git pull') before pushing again.  See the
  'Note about fast-forwards' section of 'git push --help' for details.
  </code></pre>
  
  <p>I got this error many times and can't figure out what to do.</p>
