# Cachix The cachix directory simple captures the output of `sudo cachix use` for the developers personal cache, as well as the nix-community cache. You can easily add your own cache, assuming the template lives in /etc/nixos, by simply running `sudo cachix use yourcache`. These caches are only added to the system after a `nixos-rebuild switch`, so it is recommended to call `cachix use divnix` 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.
