title: Can I clone a git repo if it already exists?
body: <p>I've started to use git 'properly' now so I have websites that use git repo's that I downloaded as zip files and uploaded to my server manually.</p>
  
  <p>Now I know to just clone to repo using SSH and then update via SSH.</p>
  
  <p>So if I have a repo on my server, is there a command I can run to apply the .git directory etc? From then on I will be able to update via SSH rather than downloading a repo manually and uploading via FTP.</p>
