 ## users
 
-this flake is built for a multi-user experience per host, enforced by `modules/user.nix`, and found in the `default.nix` file for each host.
-
-as this is a multi-user setup, the `dotfiles` group will be used for read and write access to the flake

-## development
-
-to build the system, run `sudo nixos-rebuild switch --flake .#server`
-
-please periodically run `nix flake update` to make sure we arent slacking on package versions
-
-before committing, please run `nix flake check` and make sure everything is ok

-- remove the lua static stuff from nginx + maybe cloudflare ips too
+- remove the lua static stuff from nginx + maybe cloudflare ips too + redis
 - per-host architecture selection, atm it is hardcoded to `aarch64`
 - some weird perl error abt locales when building using doas - `keepEnv` might fix this
+- move common config such as bootloader and networking settings to [`default.nix`](./default.nix)
+- swap back to hardened kernel
 - leverage nixos-hardware
-- somehow add desktop evironments and per-user dotfiles while keeping a multi-user setup
+- somehow add desktop evironments and per-user dotfiles while keeping a multi-user setup - we can always give this up if needed
