# The `nixpkgs.lib.nixosSystem` function is used to build this configuration, the following attribute set is its parameter.

# Each parameter in the `modules` is a Nix Module, and there is a partial introduction to it in the nixpkgs manual:
# <https://nixos.org/manual/nixpkgs/unstable/#module-system-introduction>
# It is said to be partial because the documentation is not complete, only some simple introductions
# (such is the current state of Nix documentation...)
# A Nix Module can be an attribute set, or a function that returns an attribute set.
# If a Module is a function, according to the Nix Wiki description, this function can have up to four parameters:
#
# config: The configuration of the entire system
# options: All option declarations refined with all definition and declaration references.
# pkgs: The attribute set extracted from the Nix package collection and enhanced with the nixpkgs.config option.
# modulesPath: The location of the module directory of Nix.
#
# Only these four parameters can be passed by default.
