About branches

Use a branch to isolate development work without affecting other branches in the repository. Each repository has one default branch, and can have multiple other branches. You can merge a branch into another branch using a pull request.

Once you're satisfied with the changes in your branch, you can open a pull request to merge your branch (the head branch) into another branch (the base branch). For more information, see "About pull requests."

You can also use a branch to publish a GitHub Pages site. For more information, see "What is GitHub Pages?"

You must have write access to a repository to create a branch, open a pull request, or delete and restore branches in a pull request. In repositories where you have owner or admin access, you can change the default branch.
