this is the video that made me jump into NixOS for every machine I have...

It can be challenging, but never forget that Nix is a language, a package manager and an OS. You can start with the package manager on the OS you already have (note: I went straight to the OS on a spare computer and a month later moved my config to all my other machines, portability and reproducibility is where Nix shines)

Once you have been inside the Nix rabbit hole, you can't to back 😉
