title: How to push to github from cloud9?
body: <p>I am trying to push some changes from cloud9 to a github repository but I am hitting a roadblock.</p>
  
  <p>I can clone OK with ssh, and everything seems to be OK, I make my changes, save the changes in cloud9 (when I go back the changes are still there), then I do <code>git commit</code> and get:</p>
  
  <pre><code>no changes added to commit (use "git add" and/or "git commit -a")
  </code></pre>
  
  <p>but I just need to commit changes to an existing file not to add. So obviously when I try to <code>git push origin master</code> there's nothing to push.</p>
  
  <p>I tried with multiple github repos and I get the same result.</p>
  
  <p>What am I missing? </p>
  
  <p>Any help appreciated!</p>
  
  <p>P.S. Oh, btw I suck at git</p>
