At the heart of GitHub is an open source version control system (VCS) called Git. Git is responsible for everything GitHub-related that happens locally on your computer.
To use Git on the command line, you'll need to download, install, and configure Git on your computer.
If you want to work with Git locally, but don't want to use the command line, you can instead download and install the GitHub Desktop client. For more information, see "Getting Started with GitHub Desktop."
If you don't need to work with files locally, GitHub lets you complete many Git-related actions directly in the browser, including:
Setting up Git
Next steps: Authenticating with GitHub from Git
When you connect to a GitHub repository from Git, you'll need to authenticate with GitHub using either HTTPS or SSH.
Connecting over HTTPS (recommended)
Connecting over SSH
Congratulations, you now have Git and GitHub all set up! What do you want to do next?
