This repository provides a GitHub Actions-based continuous integration pipeline for building custom OpenWrt firmware specifically for the Xiaomi AX3000T router. It contains a pre-configured build configuration (`.config`), custom feed scripts (`diy-part1.sh`, `diy-part2.sh`), and a comprehensive workflow file that orchestrates the entire build process: cloning the LEDE source tree, applying customizations (including passwall2, ddns-go, Argon theme, and UA3F), and compiling the firmware. The repository also includes detailed documentation for unlocking SSH on the stock firmware, flashing the custom build, and reverting to the official Xiaomi firmware. While the repo is not a traditional software application, it serves as a build configuration and automation project for embedded Linux firmware development. The codebase is tightly coupled to the specific hardware and build process, offering no reusable software components outside of the OpenWrt build context.
