+==========================================
+Move distribution guidelines to a Git repo
+==========================================
+
+- Date proposed: 2021-08-13
+- RFC MR: https://gitlab.archlinux.org/archlinux/rfcs/-/merge_requests/0005
+
+Summary
+-------
+
+Put distribution guidlelines in a Git repository and enforece a review process.
+
+Motivation
+----------
+
+Currently, distribution guidelines (packaging guidelines, etc.) are in the Arch
+Wiki. As the Arch Wiki is open to the public for edits, anyone can change the
+guidelines. Having the guidelines in this format fuments lack of discussion, as
+there is no review process enforced. Review is solely based on people watching
+the wiki page and noticing changes. This results in low-quality and inconsistent
+guidelines. Lastly, the discussion process (via the wiki talk page) is not very
+friendly, which has surely demotivated/stopped people from contributing to the
+discussions.
+
+Specification
+-------------
+
+The guidelines in the Arch Wiki, should be moved to a new repository on our
+Gitlab instance.
+
+All changes must be reviewed by at least one Arch Linux staff member, other than
+the author.
+
+Large changes (changes that substancially change core of the guidelines) must
+go through the RFC process.
+Additionally, during the review of a guideline change, any Arch Linux staff may
+request the discussion to be moved to the RFC process, and this request shall be
+honored if it is backed by at least one other staff member.
+
+Drawbacks
+---------
+
+Having the guidelines in a Gitlab repo and enforcing a review process will
+higher the bar for contributions.
+
+Unresolved Questions
+--------------------
+
+Should we have assigned reviewers for each guidelines?
+
+Alternatives Considered
+-----------------------
+
+We could add a review process to the guidelines and still keep them in the Arch
+Wiki, though I believe moving then to a Git repo is just easier.
