## Nix
If you're on [NixOS](https://nixos.org/), or have Nix installed on Linux or macOS, run `nix-shell` from the repository root to get a build environment.
By default, this will download compilers for both AVR and ARM. If you don't need both, disable the `avr` or `arm` arguments, e.g.:
nix-shell --arg arm false
## Mac
If you're using [homebrew,](http://brew.sh/) you can use the following commands:
brew tap osx-cross/avr
