title: Git push "permission denied"
body: <p>I am attempting to push my code to my github account, however whenever I try, i get this</p>
  
  <pre><code>Pushing to git@github.com:AlphaModder/Space-Dimension-Mod.git
  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>Question: how can I avoid that "Permission Denied"? Is the GitHub remote address a valid one?</p>
