how can I try this on my machine?

I'm new to flakes, can I simply do:

sudo nixos-rebuild test --flake

Then reboot? Maybe this should be clear to me from the readme, but I've read it a couple times and don't know how.

I can extend the README soon, but you'd want to do a few things:

1. Fork + clone this somewhere so that you can hack on it, personalize it.
2. Update the mysystem attribute in the flake to be the hostname of your machine.
3. Update the actual configuration.nix to be your config, or import your config/hardware-info, etc
4. Then you'd run sudo nixos-rebuild switch --flake '.#' or sudo nixos-rebuild switch --flake '.#systemname' from the repo directory.

Also, consider https://github.com/nrdxp/nixflk which is a more fully featured, more structured and opinionated config than this barebones example. In fact, I might try to get rid of this repo and merge some README stuff into nixflk. IDK if @nrdxp thinks anything in this repo currently is uniquely useful. I mostly made it to interactively assist some folks in #nixos that needed help understanding flakes.
