However, if you end up liking what you see, I think NixOS is the best way to use Nix. Just recently, I ended up wiping my hard drive. I re-partitioned and then ran one single command. After letting it build, I could boot into an operating system identical to how I had left it, with all my tools installed and configuration settings set. That's pretty hard to beat. You can see my personal config on Github.
This post will show you how I'm using Nix to manage my Python environment and dependencies for using Jupyter Notebooks for school assignments. However, this same strategy can be used to build environments for whatever tool you need.
A Nix Flake is just an object - check out those surrounding curly braces. This object has two keys, inputs and outputs. The inputs are where we define the flake's dependencies and where to find all the tools we use. This one has two, nixpkgs and flake-utils. Each of these just points to a GitHub URL, and if you follow those links, you'll see each repo provides its own flake.nix. The outputs of each remote flake get piped into the inputs of my flake, so we can use what they provide.
