Getting started with Git

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.

Git uses a username to associate commits with an identity. The Git username is not the same as your GitHub username.

If you're cloning GitHub repositories using HTTPS, we recommend you use GitHub CLI or Git Credential Manager (GCM) to remember your credentials.

If Git prompts you for a username and password every time you try to interact with GitHub, you're probably using the HTTPS clone URL for your repository.

You'll need to update your saved credentials in the git-credential-osxkeychain helper if you change your username, password, or personal access token on GitHub.

GitHub flow is a lightweight, branch-based workflow that supports teams and projects that deploy regularly.

GitHub's collaborative approach to development depends on publishing commits from your local repository to GitHub for other people to view, fetch, and update.

Learn to work with your local repositories on your computer and remote repositories hosted on GitHub.

Use a text editor to open and edit your files with Git.

To avoid problems in your diffs, you can configure Git to properly handle line endings.

You can configure Git to ignore files you don't want to check in to GitHub.
