title: How to attach my repo to heroku app
body: <p>I create a heroku app and then my machine crashed. I have a new machine. How do I attach my existing app to heroku app. When I visit heroku page the url for my app is like this</p>
  
  <pre><code>git@heroku.com:myapp.git
  </code></pre>
  
  <p>I can't do clone this app because I already have <code>myapp</code> from github. So I need to add heroku as remote to my existing github app. Anyone knows the syntax.</p>
