+# RustGCC
+
+This repository is a POC of a hitbox-style controller using an RP2040 / Pico that implements the joybus protocol, with firmware written in Rust.
+
+To get started in a ready-to-go development environment, download and install [Nix](https://nixos.org/download.html), then [enable flakes](https://nixos.wiki/wiki/Flakes) and run `nix develop .` in the root of this repository.
+
+To build the firmware, run `nix build .#` in the root of this repository.
