+There's a file [docker-compose.yml](docker/docker-compose.yml) prepared in this repo, which can be used with recent Docker version to
 provide a backend. You just need to alter this file and comment out the ```monitor``` service. What remains is
 the ```zeebe``` service, which then can be started via ```docker compose up``` command.
 
+There are several profiles in the file for running services in the prepared configuration.
+They can be specified in a file [.env](docker/.env), by passing multiple --profile flags or a comma-separated list for the COMPOSE_PROFILES environment variable:
+* ```docker compose --profile hazelcast --profile hazelcast_in_memory up```
+* ```COMPOSE_PROFILES=hazelcast,hazelcast_in_memory docker compose up```
+
+Now there are only these configuration presets:
+* ```COMPOSE_PROFILES=hazelcast,hazelcast_in_memory```
+* ```COMPOSE_PROFILES=kafka,kafka_in_memory```
+* ```COMPOSE_PROFILES=hazelcast,hazelcast_postgres,postgres```
+* ```COMPOSE_PROFILES=hazelcast,hazelcast_mysql,mysql```
+
 With such a backend running, you can simply start debugging the ```ZeebeSimpleMonitorApp``` class in your IDE of choice.
