The default branch is considered the "base" branch in your repository, against which all pull requests and code commits are automatically made, unless you specify a different branch.
Your default branch is named
master. If you have admin rights over a repository on GitHub, you can change the default branch on the repository.
- Open your repository on GitHub.
- Click Settings.
- Change the default branch using the default branch dropdown.
You can only switch between branches that already exist on GitHub. To create a new branch through the UI, see "Creating and deleting branches within your repository".
