Installing Git

The source code for this book is managed with Git, so the easiest way to access it is to use Git. Also, Heroku relies on Git for managing the deployment process and pushing code from your development machine into a live environment. You need to install Git if you don’t already have it.

You can verify whether you have it with a simple terminal command:

$ git --version

If this command responds with a version number, you already have it installed and can move to the next section. If not, you need to install Git.

A good starting point for macOS and Windows users who are new to Git is to download and install the GitHub user interface from https://help.github.com/articles/setup-git.

You don’t need a GUI, though, and you can install Git by itself by following the instructions on the main Git website at https://git-scm.com/downloads.
