+14. ### Commit messages
+   Project commit message formatting should be obeyed
+   [link](https://github.com/openbmc/docs/blob/master/CONTRIBUTING.md#formatting-commit-messages)
+
+   Commit messages should answer the following questions:
+   - Why are the changes useful?  Given that bmcweb is a user-facing daemon,
+      commits adding new functionality should include statements about how the
+      commit in question is useful to the user.
+
+   - What changes would a user expect to see?  This includes new parameters, new
+     resources, and new or changed properties.  Any route changes should be
+     explicitly called out.
+
+   - Are there compatibility concerns?  Is this change backward compatible for
+     clients?  If not, what commit would be broken, and how old is it?   Have
+     clients been warned? (ideally on the mailing list) link the discussion.
+
+   Commit messages should be line wrapped 50/72.
+
+15. ### Compatibility
+   "Don't make your users mad" Greg K-H
+   [source](https://git.sr.ht/~gregkh/presentation-application_summit/tree/main/keep_users_happy.pdf)
+
+   The kernel has very similar rules around compatibility that we should aspire
+   to follow in the footsteps of.
+
+   To that end, bmcweb will do its' best to insulate clients from breaking api
+   changes.  Being explicit about this ensures that clients can upgrade their
+   OpenBMC version without issue, and resolves a significant bottleneck in
+   getting security patches deployed to users.  Any change that's visible to a
+   user is potentially a breaking change, but requiring _all_ visible changes to
+   be configurable would increase the software complexity, therefore bmcweb
+   makes exceptions for things which a client is reasonably expected to code
+   against:
+   - New items added to a collection
+   - Changes in UID for hypermedia resources (In line with Redfish spec)
+   - New properties added to a resource
+   - New versions of a given schema
+
+   Special note: Code exists in bmcweb that is missing upstream backends to
+   make it function.  Given that compatibility requires the ability to use and
+   test the feature in question, changes to these methods, including outright
+   removal, does not constitute a breaking change.
+
+   Security: There may be cases where maintainers make explicit breaking changes
+   in the best interest of security;  In these rare cases, the maintainers and
+   contributors will endeavor to avoid breaking clients as much as is
+   technically possible, but as with all security, impact will need to be
+   weighed against the security impact of not making changes, and judgement
+   calls will be made, with options to allow providing the old behavior.
