How to Link a Git Folder with an Existing Heroku App

1. Follow this guide to get Heroku setup on your command line tool of choice.
2. heroku git:remote -a project_name

where project name is the name of your Heroku app (if your app's URL is stellablog.herokuapp.com, project_name would be stellablog) and you're done! Your local Git folder will be linked with your Heroku app, and you can deploy your latest code to it.

How to Push a Local Branch to a Separate Remote Branch

This is my first post about Git! I'll be talking about how to push the contents of a local branch to a remote branch that is different from what it currently points to. The base syntax is

git push remote local_branch:remote_branch

An example of when to use this is in combination with Heroku. You might want to push your local branch to Heroku's master branch:

git push heroku foo_branch:master

That is also how you make Heroku run a non-master git branch.

Maybe you want to push the contents of your current branch to another branch on git:

git push origin foo_branch:bar_branch
