title: How do I connect a local folder to an existing github repo?
body: <p>I made a repo on my laptop. It has a project page on github.com.</p>
  
  <p>I'm now working on my desktop computer. I manually copied over some files because I didn't think I would need every file from the repo (so I didn't clone the repo onto my desktop). How can I connect my desktop local folder with the existing repo so that I can push the files on my desktop to the repo (the desktop files are now the most recent versions of those files, since I stopped working from my laptop)</p>
