title: Permanently add an SSH key
body: <p>To get access to my remote git I add a reference to the SSH every time I push or pull:</p>
  
  <pre><code>GIT_SSH_COMMAND="ssh -i ~/.ssh/id_bit_rsa" git pull origin master
  </code></pre>
  
  <p>Is there a way to have the git remember the SSH so I don't need to add it each time?</p>
