ImmortalWrt is a fork of [OpenWrt](https://openwrt.org), with more packages ported, more devices supported, better performance, and special optimizations for mainland China users.
Compared the official one, we allow to use hacks or non-upstreamable patches / modifications to achieve our purpose. Source from anywhere.
