 * `.yml` is the default configuration format since version 8. You can find an [example configuration file](https://github.com/GIScience/openrouteservice/blob/main/ors-config.yml) with all available configuration options. Only a minimal set of properties is active, all others are commented out.
 * `.env` files for Docker setup. There is also an [example env file](https://github.com/GIScience/openrouteservice/blob/main/ors-config.env) that you can download and customize. 
-* `.json` config file: In the past openrouteservice was configured [via JSON file](json.md). This configuration method has been **deprecated** and will be eventually removed. Therefore, we strongly discourage you from using it. If you have an old JSON config, please consider to [migrate to the new config](migrate-from-json.md).

 The "old" configuration method is supported for a while for convenience. 
 The description below is kept as long as openrouteservice still supports configuration via JSON file, 
 but we do **not** recommend using this configuration method.
