+Some notes:
 
 - To use a custom Wikibase instance, you can set the subkeys of the `wikibase` property. Both `instance` and `sparqlEnpoint` are necessary. By default, Wikidata is used.
 - wikidata-jskos supports saving, editing, and deleting mappings in Wikidata. To enable this, you will need to provide `auth.algorithm` and `auth.key` (algorithm and key to decode the JWT, usually coming from [login-server]), as well as `oauth.consumer_key` and `oauth.consumer_secret` (for your registered OAuth consumer).
 - `auth.key`/`AUTH_KEY` contain line breaks. In JSON, these can simply be set as `\n`. When using `.env` or `env_file`, the whole key needs to be double-quoted (`"-----BEGIN PUBLIC KEY-----\n..."`). To set `AUTH_KEY` directly in `docker-compose.yml` via `environment`, please look at the included [`docker-compose.yml`](./docker/docker-compose.yml) file or refer to [this StackOverflow answer](https://stackoverflow.com/a/53198865).
 - Please provide a `baseUrl` when used in production. If no baseUrl is provided, `http://localhost:${port}/` will be used.
