How to link a folder with an existing Heroku app

Question

I have an existing Rails app on GitHub and deployed on Heroku. I'm trying to set up a new development machine and have cloned the project from my GitHub repository. However, I'm confused as to how to link this folder up to Heroku. Originally, I used the heroku create command, but obviously, I don't want to do that this time since it will create another Heroku instance.

Heroku project is based on the Heroku git remote. 

To add your remote in current repository use:

git remote add Heroku [email protected]:project.git

Here the project is the name of Heroku project. After this, you can use the HerokuXXXX commands and push the changes to Heroku using 

git push Heroku master
