title: Still have to login after testing SSH connection
body: <p>I was testing my SSH connection.
  After attempting to ssh to github: <code>$ ssh -T git@github.com</code> I got the following message:
  <code>Hi Parsa237! You've successfully authenticated, but GitHub does not provide shell access.</code></p>
  <p>I thought that it means I won't have to provide my username and password everytime I do a command like <code>git pull</code>.
  Yet when I did <code>git pull</code> I still had to give my username and password.</p>
  <p>Also my SSH key on github was never used:</p>

  <p>How do I solve this problem?</p>
  <p>Thanks in advance!</p>
