+## How to use this image
+### ... with 'docker run'
+To start an Armagetron Advanced server with `docker run`:
+```shell
+docker run \
+  -p 4534:4534/udp \
+  -v armagetron_data:/armagetronad \
+  evoesports/armagetronad:latest
+```
+
+### ... with 'docker compose'
+To do the same with `docker compose`:
+```yaml
+version: "3.8"
+services:
+  armagetron:
+    image: evoesports/armagetronad:latest
+    ports:
+      - 4534:4534/udp
+    volumes:
+      - armagetron_data:/armagetronad
+volumes:
+  armagetron_data:
+```
+In both cases, the server will launch and be bound to port 4534 UDP.
+The server only needs one volume to store all your data, which is mounted to /armagetron. You can also use bind mounts.
