 ## MLAT Configuration
 
-By default, MLAT is switched ON in the container. Please make sure to configure a valid `MLAT_HOST`, `LAT`, `LON`, and `ALT` in your `docker-compose.yml` setup. If you want to switch off MLAT, simply set `MLAT_HOST` to empty. You will see a message in the logs encouraging to configure MLAT, followed by a message saying that MLAT is disabled.
