-## Upgrading the recipe
-
-**NOTE** This section is only intended for [recipe maintainers][maintainers]
-
-Minor/patch updates usually work OK with `abra recipe upgrade` and friends. 
-
-For major updates:
-
-1. Go to https://setup.mailu.io/ and generate a new config
-2. Download the new config and compare it to `compose.yml`. Pay attention to:
-  - New / removed services
-  - Added/removed config options
-  - Changes to networking
-3. Test upgrading from the previous version to the new version
-4. `abra recipe sync` / `abra recipe release` as normal
