+If you run Docker on a OS that doesn't run Docker natively or in a VM, such as on Windows or macOS, you may want to to run the ClientSDK and your game server container together with [Docker Compose](https://docs.docker.com/compose/). To do so, create a `docker-compose.yaml` file setup with a network overlay shared between them:
+
+```yaml
+version: '3'
+services:
+  gameserver:
+    build: . # <path to build context>
+    ports:
+      - "127.0.0.1:7777:7777/udp"

+    configs:

 ## Running from source code instead of prebuilt binary
 
 If you wish to run from source rather than pre-built binaries, that is an available alternative.
