About forks

A fork is a copy of a repository that you manage. Forks let you make changes to a project without affecting the original repository. You can fetch updates from or submit changes to the original repository with pull requests.

Forking a repository is similar to copying a repository, with two major differences:

  • You can use a pull request to suggest changes from your user-owned fork to the original repository, also known as the upstream repository.
  • You can bring changes from the upstream repository to your local fork by synchronizing your fork with the upstream repository.

您可以将仓库复刻到您的用户帐户或具有仓库创建权限的任何组织。 For more information, see "Roles in an organization."

如果您可以访问私有仓库且所有者允许复刻,则您可以将该仓库复刻到您的用户帐户或者 your GitHub Enterprise Server instance 上您具有仓库创建权限的任何组织。

您可以使用 GitHub Desktop 复刻仓库。 更多信息请参阅“从 GitHub Desktop 克隆和复刻仓库”。

Deleting a fork will not delete the original upstream repository. You can make any changes you want to your fork—add collaborators, rename files, generate GitHub Pages—with no effect on the original.

In open source projects, forks are often used to iterate on ideas or changes before they are offered back to the upstream repository. When you make changes in your user-owned fork and open a pull request that compares your work to the upstream repository, you can give anyone with push access to the upstream repository permission to push changes to your pull request branch. This speeds up collaboration by allowing repository maintainers the ability to make commits or run tests locally to your pull request branch from a user-owned fork before merging. You cannot give push permissions to a fork owned by an organization.

私有复刻继承上游或父仓库的权限结构。 例如,如果上游仓库是私有的,并授予团队读/写访问权限,则同一团队对该私有上游仓库的任何复刻拥有读/写权限。 这有助于私有仓库的所有者保持对其代码的控制。

If you want to create a new repository from the contents of an existing repository but don't want to merge your changes to the upstream in the future, you can duplicate the repository or, if the repository is a template, you can use the repository as a template. For more information, see "Duplicating a repository" and "Creating a repository from a template".
