Honestly you should ! Unless you want to do crazy stuff you actually don’t need to learn the entire documentation.

I was able to setup full disk encryption with encrypted boot loader pretty easily, there are great tutorials out there. I’m going to figure out Secure Boot next.

The nice thing is that once you’ve managed to do something, it’s in your config forever. My main problem with Arch was the absence of rollbacks, and having to remember all the stuff you do when installing it that you inevitably forget before the next time your system breaks and needs a reinstall. There’s none of that with Nix, and it’s awesome.
