This step is the heart of deployment as far as Heroku apps are concerned. Deploying a Heroku app is as simple and uncomplicated as issuing the following command:

git push heroku master

And as they say, the rest is magic!

In this chapter, we will delve a little more into Git—the collaborative version control system used for Heroku application development. We will also touch on topics that are key to understanding deployment on Heroku and facilities in the platform, topics that help in making Heroku such an easy and efficient deployment platform.
