# Licensing

**Functions:**

* **Serial Number:** Displays the unique serial number (nomos) of the controller.
* **Status:** Indicates whether the nomos controller is properly licensed.
* **Update Online Licenses:** This button allows you to update licenses over the internet. This is useful when new licensing terms or features have been added.
* **Cancel:** Use this button to cancel the licensing process and go back to the previous view.

**Note:**

It is important that the nomos controller is licensed to make sure all functions and updates work correctly. The licensing process is usually linked to the serial number of the device.
