title: Setting up Github on a new computer
body: <p>I am an almost perfect beginner at Github so please humor me with this elementary question.</p>
  
  <p>I have a laptop PC that I've been using to interact with a repo on Github. I just bought a Mac and I would like to do my programming on both machines.</p>
  
  <p>I have installed Git on the new machine and I have set up my username, e-mail, and Github token on the Terminal. </p>
  
  <p>What are the basic commands I need to do this:</p>
  
  <ol>
  <li>Download the repo from Github the first time? I've created a new folder on my Mac but going there and typing <code>git pull git@github.com/sscirrus/repo.git</code> produces <code>fatal: not a repository (or any of the parent directories): .git</code>.</li>
  <li>Upload those changes again such that the main repo is updating cleanly with each new push. I assume that once I have the code in my new folder, it would be a matter of <code>git add .</code> and <code>git push</code> with password entry?</li>
  </ol>
  
  <p>I am reading through tutorials on Git but just want to make sure I'm doing something sensible for my situation before my newbieness screws up a lot of prior work. Thank you!</p>
