You can change a repository's visibility from private to public if you're an organization owner or have admin permissions for the repository.
Tip: If you're converting your private repository to a public repository as part of a move toward creating an open source project, see the Open Source Guides for helpful tips and guidelines.
Warning: When a private repository is made public, its private forks are detached. For more information, see "What happens to forks when a repository is deleted or changes visibility?"
On GitHub Enterprise, navigate to the main page of the repository.
Under your repository name, click Settings.
Click Make public.
- Read the warnings.
- Type the name of the repository that you want to make public.
- Click I understand, make this repository public.
