Some key advantages include:
* A single home for all your Nix expressions, easily sharable and portable!
* Skip the setup, simply use the included [nix-shell](./shell.nix) or
* Skip the boilerplate, simply use the included [nix-shell](./shell.nix) or
[direnv][direnv] profile and get up and running with flakes right away.

You can make an ISO and customize it by modifying the [niximg](./hosts/niximg.nix)

## Use a Package from NUR
NUR is wired in from the start. For safety, nothing is added from it by default,

```nix
{ pkgs, ... }:

environment.systemPackages = with pkgs; [ nur.repos.<owner>.<package> ];
}
```
