+  and fulfil the responsibilities described below.
+- **Contributors with merge access** Trusted people can open pull requests and merge them

 - Has to watch the repository (to get notifications)

+
+| Type of change | Approval needed |
+| --- | --- |
+| Security fix | No, can be merged immediately |
+| Regular update | No, after a review window of about one week |
+| Feature, extension or change of the default configuration | Yes, always |
+| Small change that can't break the recipe | No |
+
+### Security fixes
+
+If a pull request contains a relevant security fix, the person who opened it is
+allowed to merge it directly, without approval and without waiting.
+
+The same applies to a pull request that fixes an update which contains a
+security fix: if a version bump can't be merged as it is, because the new
+version needs changes to the configuration, then the pull request that
+makes that update work can be merged directly as well. Otherwise a broken
+update would block a security fix.
+
+Keep these pull requests as small as possible, so they contain nothing but what
+is needed to get the fix out.
+
+### Regular updates
+
+If a pull request rolls out a regular update, there is a time window of about
+one week for other maintainers to review it and to request changes. If no other
+maintainer is available within this time window, the person who opened it is
+allowed to merge it without approval.
+
+### Features, extensions and default configuration
+
+Any pull request that adds a feature or an extension, or changes the default
+configuration, needs an approval, no matter who opened it. These are the
+changes most likely to break existing deployments.
+
+### Small changes
+
+Small changes that definitely won't break the recipe can be merged without
+approval, for example:
+
+- a new environment variable that is commented out by default
+- a new `abra.sh` function
+- changes to the [README.md](./README.md)
+- writing new tests
+- configuring renovate
+
+If a pull request falls into more than one of these categories, the stricter
+rule applies. If you are unsure which category a pull request belongs to, ask
+for an approval.
+
+Even though it is okay to merge a pull request with a single approval, it is
+always better if all maintainers looked at the pull request and approved it.
 
 ## Become a maintainer
 
 Everyone can apply to be a recipe maintainer:
+
 1. Watch the repository to always get updates
 2. Simply add your self to the list in the [README.md](./README.md) and open a new pull request with the change.
 3. Once the pull request gets merged you will be added to the [traefik maintainers team](https://git.coopcloud.tech/org/coop-cloud/teams/traefik-maintainers).
+4. Join the room [#cc-|-traefik-maintenance:matrix.org](https://matrix.to/#/%23cc-%7C-traefik-maintenance:matrix.org) and chat to other maintainers.

 ## Enabling onion service
 
 Uncomment the line in the config setting `ONION_ENABLED=1`. This will create a new entrypoint on port 9052 which can be used to bypass forced SSL. For more details, see the [onion recipe](https://recipes.coopcloud.tech/onion).
