+### Setup notes
+
+Kafka must be connectable from both `localhost` (for cli) and `kafa` (the docker container name). 
+
+
+### Useful commands
+
+#### Powershell
+
+```shell
+# might help with mounting the unix socket on Windows? 
+$Env:COMPOSE_CONVERT_WINDOWS_PATHS=1 
+
+# full rebuild
+docker-compose down; docker-compose build; docker-compose up -d; docker-compose logs -f
+
+```
+
+#### zsh
+
+```shell
+# listen to events from factorio-server
+docker logs --tail 0 -f factorio-server | sed -n -e 's/^FactorioEvent: //p' 
+
+# tail logs with docker api (except it doesn't work)
+curl -vvv \ 
+  --unix-socket /var/run/docker.sock \
+  --no-buffer \
+  --header "Connection: Upgrade" \
