+## Scaling
+
+Docker compose does not support horizontal scaling without an additional Load Balancer component.
+We recommend to use one of the other deployment options if your load exceeds single-instance scale or requires high availability.
+To add more throughput on a docker compose setup, you can usually use a larger virtual machine, i.e. scale vertically.

 ## Shutdown
 
 You can stop the containers by hitting `Ctrl+C` in the terminal.
