+# Fonctionnement de flake
+
+### Général
+
+- Permet de télécharger des dépendances de code comme \<home-manager>
+> Stocke les dépendances dans le fichier `flake.lock`.
+> Si l'on souhaite figer la version des dépendances pour éviter tout risque de mauvaise configuration. On peut utiliser le fichier `flake.log`
+
+- Permet de configurer facilement notre propre configuration comme depuis les dotfiles
+
+### Installation
+
+Pour le moment, flake est encore expérimental donc il faut l'activer manuellement.
+
+/etc/nixos/configuration.nix
+```nix
+[...]
+  # BEGIN: Add flake feature TODO: Remove when not experimental
+  nix = {
+    package = pkgs.nixFlakes;
+    extraOptions = "experimental-features = nix-command flakes";
+  };
+  # END: Add flake feature
+}
+```
+
+### Configuration initial
+
+Génére le fichier `flake.nix`
+```bash
+nix flake init
+```
+
+`flake.nix`
+```nix
+{
+  description = "A very basic flake";
+
+  outputs = { self, nixpkgs }: {
+
+    packages.x86_64-linux.hello = nixpkgs.legacyPackages.x86_64-linux.hello;

+#### Outputs

+- Permet de configurer ce que l'on a importé.
+- Peut configurer les packages, configurations, modules, ...
