• Setup Procfile as per https://devcenter.heroku.com/articles/getting-started-with-rails4#webserver

• Do this step if you create your Heroku account online
• Log on to your heroku account
• Go to your app and change your app name
• Change your app name in /.git/config [remote "heroku"]

[remote "heroku"]
	url = git@heroku.com:<YOUR_NEW_APP_NAME>.git
	fetch = +refs/heads/*:refs/remotes/heroku/*

Push to heroku

• Commit master branch to heroku
• Make sure you have already setup your git
