NixOS is a Linux distribution.
It is build on top of the nix package manager.
Unlike other common Linux distros, it does not have a apt or yum type package manager to install software.
Instead, nix allows you to install software either via a declarative configuration file or in a temporary shell environment.

General Notes on My Config
I use KDE Plasma 6 for my Desktop Environment
I’ve tried GNOME, I hated how rudimentary it was. KDE Plasma as their tag suggests is simple when you see it but powerful when you need it.
Most important of all, it has by far the best Desktop Window tiling support, right out of the box. All of the Virtual-desktop and Window snapping shortcuts match the excellent Windows shortcuts, so my keyboard macros work out of the box.
