 **If accessing the Web UI from a remote machine**, you need to set up port forwarding.
 
+First, find your Spark's IP address. On the Spark, run:
+
+```bash
+hostname -I | awk '{print $1}'
+```
+
+This prints the primary IP address (e.g. `192.168.1.42`). You can also find it in **Settings > Wi-Fi** or **Settings > Network** on the Spark's desktop, or check your router's connected-devices list.

 Start the port forward on the Spark host:
 
 ```bash
 openshell forward start 18789 my-assistant --background
