- Projects, the all-new projects experience, is now available. For more information about Projects, see "About Projects" and for information about migrating your classic project, see "Migrating from projects (classic)."
- You can only create a new classic project board for an organization or user that already has at least one classic project board. You cannot create new classic projects for repositories. If you're unable to create a classic project board, create a project instead.
Anyone with write permissions to a classic project can link repositories owned by that organization or personal account to the classic project. For more information, see "Project (classic) permissions for an organization" or "Permission levels for a project board owned by a personal account."
You can link up to twenty-five repositories to your organization or user-owned classic project. Linking repositories makes it easier to add issues and pull requests from those repositories to your classic project using Add cards or from the issue or pull requests sidebar. You can add issues and pull requests from any unlinked repositories by typing the issue or pull request URL in a card. For more information, see "Adding issues and pull requests to a project (classic)."
Navigate to the classic project where you want to link a repository.
On the top-right side of the classic project, click Menu.
Click , then click Settings.
In the left sidebar, click Linked repositories.
Click Link a repository.
Search for the repository you'd like to link.
Click Link. To unlink, click Unlink.
Note: In order to link a repository to your organization or user owned classic project the repository needs to have issues enabled. That is, the repository has an "Issues" tab (in forked repositories issues are disabled by default). For information on how to enable or disable issues for a repository, see "Disabling issues."
