Install Git

To contribute to GitLab projects, you must download and install the Git client on your local machine. This page explains how to install and configure Git on macOS and Ubuntu Linux.

For information on downloading and installing Git on other operating systems, see the official Git website.

After you install and configure Git, generate and add an SSH key pair to your GitLab account. GitLab uses the SSH protocol to securely communicate with Git. With SSH, you can authenticate to the GitLab remote server without entering your username and password each time.

Keep Git up to date by periodically running the following command:

brew update && brew upgrade git

To start using Git from your local machine, you must enter your credentials to identify yourself as the author of your work.

You can configure your Git identity locally or globally:

Locally: Use for the current project only.
Globally: Use for all current and future projects.

Configure your Git identity locally to use it for the current project only.

The full name and email address should match the ones you use in GitLab.

git config --local user.name "Alex Smith"
```

Add your email address. For example:

git config --local user.email "your_email_address@example.com"

To check the configuration, run:
```
git config --local --list
```

Configure your Git identity globally to use it for all current and future projects on your machine.
