 * The formula is currently Linux/systemd-centric. It should be relatively easy to provide the correct parameters and service file for other platforms though.
 * Since the formula skips the web installer, you will need to provide at least the database configuration.
 * You can optionally specify the secrets, but they can be autogenerated by Salt as well. In that case, they will be saved in a grain value.
-* Secrets and database config will be written to the global config file, the rest into ``custom/conf/app.ini``.
 * All the paths are modifiable, find them in ``lookup:paths``. You should not need to set the corresponding values in your config, they are added automatically.
 * If Gitea requires mounts for some of the paths, you can specify them in ``service:requires_mount`` as a list.
-* If Gitea requires a local service unit (e.g. database server), specify it/them in ``service:wants`` as a list.
+* If Gitea requires a local service unit (e.g. Redis server), specify it/them in ``service:wants`` as a list. This formula will do its best to automatically add a locally running database service to this list.
