title: Github permission denied: ssh add agent has no identities
body: <p>This is my first time accessing GitHub and I'm not experienced using a console. I am on a MacBook using Bash. When I try to access GitHub, I get this:</p>
  
  <pre><code>git clone git@github.com:dhulihan/league-of-legends-data-scraper.git
  Cloning into 'league-of-legends-data-scraper'...
  Permission denied (publickey).
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  </code></pre>
  
  <p>I've tried following the instructions on Github page about permission being denied.</p>
  
  <p>When I use <code>ssh -vT git@github.com</code>, I get the following:</p>

  <p>Next, <code>eval "$(ssh-agent -s)"</code> returns "Agent pid 2314",
  however <code>ssh-add -l</code> returns "The agent has no identities."</p>
  
  <p>And that is where I am stuck. </p>
