Default preview style and configuration
======

- If no configuration file is specified, a default preview style (compatible with openmaptiles) is used.
- If no mbtiles file is specified (and is not found in the current working directory), a sample file is downloaded (showing the Zurich area)

Reloading the configuration
======

It is possible to reload the configuration file without restarting the whole process by sending a SIGHUP signal to the node process.

- The `docker kill -s HUP tileserver-gl` command can be used when running the tileserver-gl docker container.
- The `docker-compose kill -s HUP tileserver-gl-service-name` can be used when tileserver-gl is run as a docker-compose service.
