Link private repositories to private projects

Question

Is it possible to link private repositories to a private project? All collaborators of the private repo's are also members of the project.

I know it's possible to add a project to a private repository. But what if multiple repositories are part of the same project (and is that possible on github?).

Answer 1

Yes, it's possible in the Project settings:

https://github.com/users/{username}/projects/{projectId}/settings/linked_repositories
