First, install [nix][nix] if you don't have it.
The `shell.nix` provides a reproducible build environment for android and rust. I recommend using [direnv][direnv] to load this environment when you `cd` into the directory.

It will likely work without nix if you are just looking to do non-android dev and have the rust toolchain already installed. If you decide to use nix, I recommend using [direnv][direnv] to load the nix shell environment when you `cd` into the directory.
If you don't have [direnv][direnv], enter the dev shell via:
