How do I host a kbin instance on NixOS?

Hello, does anyone know about how to run a kbin instance on NixOS? Will the steps on https://codeberg.org/Kbin/kbin-core/wiki#admin-guide (but replacing the apt installs with adding packages in configuration.nix) just work, or is there a better, more reproducible way?

Thanks.

EDIT: I meant a kbin instance, not lemmy.
