Deleting a repository
Tip: You can follow these steps to delete forks that belong to you as well. Deleting a forked repository doesn't delete the upstream repository.
Warning: These steps will permanently delete the repository, wiki, issues, and comments. This action cannot be undone.
Please also keep in mind that:
- Deleting a private repository will delete all of its forks.
- Deleting a public repository will not delete its forks.
- Deleting all of your private repositories will not downgrade your account to a Free plan.
