+## Examples with docker compose
+
+All examples above can be used in your [`docker-compose.yml`](https://github.com/windmill-labs/windmill/blob/main/docker-compose.yml) by specifying the build context.0
+
+Replace:
+```
+  windmill_worker:
+    image: ${WM_IMAGE}
+```
+
+With the following:
+```
+  windmill_worker:
+    build:
+      context: ./path/to/dockerfile
+      args:
+        WM_IMAGE: ${WM_IMAGE}
+```
+
+Note that you can pass environment variables from your `.env` file via the args above and use them in your `Dockerfile`:
+```dockerfile
+ARG WM_IMAGE
+FROM ${WM_IMAGE}
+
+[...]
+```

 ## Init Scripts
 
 Init scripts provide a method to pre-install binaries or set initial configurations without the need to modify the base image. This approach offers added convenience. Init Scripts are executed at the beginning when the worker starts, ensuring that any necessary binaries or configurations are set up before the worker undertakes any other job.
