+If using [Docker to run ActiveWorkflow](https://docs.activeworkflow.org/#running-locally-with-docker),
+you'll need to use the `-e` parameter to `docker run` to pass `REMOTE_AGENT_URL` through
+to ActiveWorkflow. The address in the URL will also have to be updated to match where the agent
+is running (`127.0.0.1` is unlikely to be correct). Docker provides `host.docker.internal` for the host IP.
+Thus, you could run:
+```sh
+docker run -e REMOTE_AGENT_URL="http://host.docker.internal:5000/" -p 3000:3000 --rm automaticmode/active_workflow
+```
+
 Now you can start ActiveWorkflow. You should be able to create instances of this agent (named "Python Test Agent"). Run it and send messages to it.
 
 Please note that this project is just a minimal example. Consider using a proper project structure when developing your own ActiveWorkflow agents.
