 * `DOMAIN` - domain name pointing to the IP address of your node, when configured the run script will request SSL certs from Let's Encrypt and run Waku node with WebSockets Secure (WSS) options enabled (e.g. `DOMAIN=waku.example.com`)
 * `NODEKEY` - this env variable allows you to provide a node key as described in [operators documentation](https://github.com/waku-org/nwaku/blob/master/docs/operators/how-to/configure-key.md) (e.g. `NODEKEY=9f439983aa4851346cfe6e17585e426f482871a43626812e23490895cd602c11`)
 * `EXTRA_ARGS` - this variable allows you to specify additional or overriding CLI option for the Waku node which will be appended to the `wakunode2` command. (e.g. `EXTRA_ARGS="--store=false --max-connections=3000`)

+## Log monitoring and troubleshooting
+
+When running the container in detached mode, it's important to note that while notifications about successful container startup are received, any errors occurring during runtime won't be printed to the terminal.
+
+To ensure the proper functioning of the container, it is strongly recommended to monitor the logs. Pay special attention during the first minute of runtime to confirm that the node has spun up successfully.
+
+To check the status of the node, visit [http://localhost:8003/health](http://localhost:8003/health)
+
+For real-time logs of the 'nwaku' service, use the following command:
+
+```console
+docker-compose logs nwaku -f
+```
+
+In general, to view logs of any service running on Docker Compose, execute:
+
+```console
+docker-compose logs <service> -f
+```
+
+To identify different services currently running, refer to the "SERVICE" column displayed when executing:
+```console
+docker-compose ps
+```
