title: heroku collaborate without cloning
body: <p>I have been invited to join a heroku collaboration. I received the email:</p>
  
  <blockquote>
    <p>Since you already have an account with Heroku, you can get started by
    simply git cloning the app repository:</p>
    
    <p>git clone git@heroku.com:.....</p>
  </blockquote>
  
  <p>The other collaborators and myself are already pushing/pulling to the same github repo, so I already have a copy of the code.</p>
  
  <p>From the Heroku dev center (https://devcenter.heroku.com/articles/collab):</p>
  
  <blockquote>
    <p>$ heroku git:clone -a APPNAME This will create a directory called
    APPNAME, with a full copy of the git repository. It also sets up a git
    remote called heroku.</p>
  </blockquote>
  
  <p>So, what do I have to do to just setup the git remote to heroku? I know that I could just dump my copy and clone over it, but I don't want to do this.</p>
