+If you come across issues or ideas for improvements along the way, please create a pull request (or a [GitHub issue](https://github.com/HackYourFuture-CPH/program/issues), if you're not sure how to implement it) and share in #mentorroom for visibility and feedback.

+## How permissions work
+
+Permissions are managed through GitHub teams, their roles on this repo, and branch rules.
+
+- _HYF Staff_ members have the admin role (to do things like changing repo settings, inviting new contributors).
+- Members of the _Curriculum Crew_ team on GitHub have the write role (to do things like cloning, pushing branches, approving PRs - any volunteer is welcome here!).
+- One approval by anyone in _Curriculum Crew_ or _HYF Staff_ is required on a PR before merging is allowed.
+- Merging to `main` can be performed by any _HYF Staff_ member.
