title: Open Ruby on Rails project from another computer
body: <p>I'm still a beginner in developing Ruby on Rails apps. I've developed a project on my old laptop. And I want to open it on my new one. When I download the project from github, I am not able to perform "heroku open". I receive the following error:  "No app specified". </p>
  
  <p>And if I write git push heroku master, it says "Not a git repository".</p>
  
  <p>Can you help me please? Thanks a lot!</p>
