# Cachix The system will automatically pull a cachix.nix at the root if one exists. This is usually created automatically by a `sudo cachix use`. If you're more inclined to keep the root clean, you can drop any generated files in the `cachix` directory into the `profiles/cachix` directory without further modification. For example, to add your own cache, assuming the template lives in /etc/nixos, by simply running `sudo cachix use yourcache`. Then, optionally, move `cachix/yourcache.nix` to `profiles/cachix/yourcache.nix` These caches are only added to the system after a `nixos-rebuild switch`, so it is recommended to call `cachix use nrdxp` before the initial deployment, as it will save a lot of build time. In the future, users will be able to skip this step once the ability to define the nix.conf within the flake is fully fleshed out upstream.
