+============================================================
+
+Arborescence a ajouter au depot :
+
+  modules/first-login-ui.nix
+  first-login-ui/CMakeLists.txt
+  first-login-ui/org.raspot.nixosfirstlogin.desktop
+  first-login-ui/src/CMakeLists.txt
+  first-login-ui/src/main.cpp
+  first-login-ui/src/Main.qml
+
+Le configuration.nix fourni est un exemple complet base sur le depot actuel,
+avec /etc/nixos/hardware-configuration.nix et l'import supplementaire :
+
+  ./modules/first-login-ui.nix
+
+Validation prudente :
+
+  sudo nixos-rebuild build -I nixos-config=/home/localadm/nixos-workstations/configuration.nix
+  sudo nixos-rebuild dry-activate -I nixos-config=/home/localadm/nixos-workstations/configuration.nix
+  sudo nixos-rebuild test -I nixos-config=/home/localadm/nixos-workstations/configuration.nix
+
+Puis lancer MANUELLEMENT :
+
+  nixos-first-login-ui
+
+Aucun autostart n'est installe par ce nouveau module.
+Le module historique modules/yubikey-first-login.nix n'est pas modifie.
