## Overview

This repository supports a Debian/Ubuntu-based Armbian distribution for ARM devices, including unofficial TV boxes. The documented user outcome is a bootable Linux system that can be used as a server; documented capabilities include eMMC installation, kernel updates, and management commands. The supplied tree exposes shared, platform, and board-specific filesystem overlays, but not the build orchestration or most command implementations, so their wiring is not inferred.
