You can change a repository's visibility from private to public if you're either an organization owner or have admin permissions for the repository.
Tip: Only members with owner privileges for an organization or admin privileges for a repository can change a repository's settings. For more information, see "Repository permission levels for an organization."
Warning: When a private repository is made public, its private forks are detached and billed separately. For more information, see "What happens to forks when a repository is deleted or changes visibility?"
On GitHub, 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.
