 This branch is called `simple`, because that's the intent: To keep things simple:
 
-* One container. The server runs in the same container used to manage it.
-* One local bind mount. All files are stored in a directory on the host machine.
-* No root requirement. The container and its files are owned by the host user and kept entirely in that user's home directory.
-* Everything is left to the user to run by hand using commands similar to the official documentation.
+* A Debian slim image with `steamcmd` and enough utilities installed to run a DayZ server.
+* All server and steamcmd files are persisted in the host user's home directory using a bind mount.
+* Everything else is left to the user to run by hand using commands similar to the official documentation.

 ## Stop

+Hit control c to stop the server in the shell where it's running in the foreground.
 
 Otherwise, open a new shell in the container and kill the process:
 
 ```docker
+kill -TERM $(pidof DayZServer)
+```
+
+It takes time for the server to wrap things up, so always give it at least 30 seconds to fully shut down.
+
+If the process does not exit, which it some times does, then you have to kill it:
+
+```docker
+kill -KILL $(pidof DayZServer)
+```
+
+Otherwise just bring the stack down. That will kill the server process as well:
+
+```shell
+docker compose down
