 This document describes how to use the command line interface of MapSwipe Worker.
 
 In our current deployment setup the commands of the MapSwipe Workers CLI are hard-coded in the Docker-Compose File.
 
 You can run these commands also using docker-compose:
+
 ```
 docker-compose run mapswipe_workers mapswipe_workers --help
 ```
