NixOS appreciation post

So after being a long-time Fedora/RHEL/CentOS/Rocky/etc user, I finally decided to give NixOS a try after the recent RHEL news.

And BOY and I blown away. You can do so much more than I thought possible with automation on NixOS. It's incredible!

Since I"m so new, I do have a question for you all: What's your go-to resource for learning Nix/NixOS?

Thanks!
