Set up remotes for staging and production apps

Official docs found here: https://devcenter.heroku.com/articles/git#creating-a-heroku-remote

If you haven't created the heroku apps yet, you can create them and name the remotes simultaneously. I documented this here

Connect your git repo to an existing Heroku app

If you have already created your Heroku app, you can easily add a remote to your local repository with the heroku git:remote command. All you need is your Heroku app’s name:

heroku git:remote -a app-name
set git remote heroku to https://git.heroku.com/app-name.git

Check which remotes you've already set up and what their names are

git remote

Rename your remotes 'staging' and 'production'

By default, heroku names the remote heroku. you'll want to rename this to staging or production

git remote rename heroku staging
