+=== NixOS Configuration
+
+NixOS has its own "do all the things" configuration file which
+declaratively handles what things need to be done in the target
+system, and it has an existing tool to "execute" that declarative
+specification. This module takes configuration values set by
+Calamares viewmodules (e.g. the users module) and puts
+them into the configuration file in the target system,
+and then runs the necessary NixOS specific tools.
