Downloading and Installing Git

Is Git Already Installed?

You can quickly check to see if git is installed on your computer, and which version. Simply open a terminal (or command prompt) and type the following command:

git --version

If you see a version number, then Git is already installed on your computer. If you see an error message or if your version is less than 2.40, you will need to install Git.

Installation

The following videos will walk you through the installation process. Choose the corresponding video for your operating system:

Windows 10/11
Mac

To install Git, go to https://git-scm.com/downloads and download the version for your operating system.

User Configuration

Now that Git is installed, you need to configure it with your name and email address. This information will be used to identify you when you make changes to your code.

Note

If you are on campus, using a school computer, this step is not necessary. Git will use your school email address and username.

You can use your school email address, or your personal email if you prefer.

Here is the command to set your user name:

git config --global user.name "Your Name"

And here is the command to set your email address:

git config --global user.email "Your Email"

You can change your name and email address at any time by running these commands again, or by modifying the .gitconfig file in your home directory.
