## How It Works

1. Download and install the Zentanode Updater on your computer
2. Connect your Zentanode device via **USB-C cable**
3. The updater checks the current firmware version on the device
4. If a newer version is available, it downloads the update
5. The updater **flashes the device** with the new firmware
6. The device reboots with the latest software

Nodes also receive automatic over-the-air updates when idle. The USB updater is primarily for initial setup, major firmware upgrades, or troubleshooting.
