to use this cache.
You don't need the cachix binary to use the cachix cache though, you
just need to add the relevant
[`substituters`](https://nixos.org/manual/nix/stable/command-ref/conf-file.html?highlight=nix.conf#conf-substituters)

[`trusted-substituters`](https://nixos.org/manual/nix/stable/command-ref/conf-file.html?highlight=nix.conf#conf-trusted-substituters).
