I have to be honest and say it was a journey. Nix in itself isn’t really difficult I find. But everything together and finding the right documentation and figure out how NixOS comes together can be a bit daunting.

But a simple straight forward config is pretty doable. My advice is to start small and build up. You can reuse your old dotfiles and include them in the configuration directly, so you don’t have to convert everything to nix (right away). Also don’t scare away from using flakes, they are the way to go in my opinion.

You can define multiple hosts/systems in one configuration with each their own nixosSystem call.
