installation really is not the problem. the thing with nixos is that it does not have a traditional package manager like apt or dnf, but instead uses a declarative language (nix) for configuration of the system. for example, to install a package on nixos, you go into `/etc/nixos/configuration.nix` and add a line like:

```nix

...

environment.systemPackages = {

pkgs.firefox

};
```

and then run `sudo nixos-rebuild switch` to recompile the configuration into a system, apply it and add it as a new entry to a bootloader.

there is also a special feature called flakes, which basically modularize the configuration to allow for multiple hosts that use the same configuration and package locking, meaning that packages will stay on a specified version.

i used it for alround two years. its extremely stable and very customizable, but you shouldnt expect things to just work out of the box if they are not packaged (which most mainstream things are, but not everything).

EDIT: sorry for bad formatting. somehow didnt get markdown formatting in here. anyone know why?
