If you're assigned a role with the Configure Custom Repository Source Control privilege, you can specify a source control repository to use at the project level, instead of using the global source control repository that's set up for your organization.
By default, when you perform a source control action on a project or folder, the action uses the global source control repository that's set up by the organization administrator. If the organization administrator enables project-level repositories, you can link a project to a repository other than the global repository.
If you use project-level repositories, be sure to add the Repository URL and Repository Branch columns to the Explore page.
Before you link a project to a custom repository, make sure that other users who need access to the project have access to the repository.
