-### Prop Hunt Setup
-A prop hunt server can be stood up by passing the following environment variable `TF2_SERVER_PROPHUNT=true` when starting up the container. 
+The container includes a built-in health check that monitors the srcds process. Docker will automatically report the container as unhealthy if the game server stops running.
+
+## Prop Hunt Setup
+
+A prop hunt server can be stood up by passing the following environment variable `TF2_SERVER_ENABLE_PROPHUNT=true` when starting up the container.
 This will install MetaMod and SourceMod into the container as well as all the necessary assets like maps, sounds, sourcemod plugins, etc...
-*Note: It does appear the TF2 server crashes when attempting to connect to the server for the first time after standing up this type of server. Appears to be a bug, but simply connecting again appears to work fine. No further testing has been done.

+
+## Troubleshooting
+
+**Server won't start**
+- Check Docker logs: `docker logs <container_id>`
+- Verify all required ports are available and not in use
+- Ensure adequate disk space for game files
+
+**Slow startup**
+- First startup downloads ~8GB of game files
+- Subsequent startups are faster if game files are persisted via volume
+
+**Players can't connect**
+- Verify ports 27015 UDP/TCP are forwarded/exposed correctly
+- Check `TF2_SVLAN` is set to `0` for internet play
+- Ensure firewall rules allow incoming connections
