 * Unit
 
 Declarative configuration for the main server, using [[https://nixos.org][NixOS]]
+
+** Modules
+
+ The configuration is sliced into different files, per category:
+
+ - ZFS pool configuration: hardware-configuration.nix
+ - Network configuration: networking.nix
+ - Synchronization and backup services: datasync.nix
+ - Web services and reverse proxy: webstack.nix
+ - Smartd: monitoring.nix
+ - Systemd services and timers: periodic.nix
+ - Virtual machines: virtualization.nix
+
+ All the modules are imported in *configuration.nix*
