+- Rock Pi 4A/4A+
+- Rock Pi 4B/4B+
+- Rock Pi 4C
+- Rock 4C+/OKdo Rock 4C+
+- Rock 4SE

-You have a different Rock Pi board and would like to run Home Assistant on it? Please open an issue to get in contact.

-## What is supported
+## Automatic updates
+
+Since this is an unofficial fork of Homeassistant OS, the OS image cannot be updated over the air (supervisor, core and all other components can be updated just fine). You will need to reflash for each release.

+However, HA's built-in backup and restore functionality works great so there should be no dataloss. Make sure to create a "Full Backup" and download it before flashing a new image.
