+
+Do not forget to `git add` the `flake.nix` file! Or you'll face the `does not exist` error.

+
+## Simplying
+
+First step:
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+  };
+  outputs = inputs: {
+    packages."x86_64-linux".default = derivation {
+      name = "simple";
+      builder = "${inputs.nixpkgs.legacyPackages."x86_64-linux".bash}/bin/bash";
+      args = [ "-c" "echo foo > $out" ];
+      src = ./.;
+      system = "x86_64-linux";
+    };
+  };
+}
+```
+
+Second step:
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+  };
+  outputs = { self, nixpkgs }: {
+    packages."x86_64-linux".default = derivation {
+      name = "simple";
+      builder = "${nixpkgs.legacyPackages."x86_64-linux".bash}/bin/bash";
+      args = [ "-c" "echo foo > $out" ];
+      src = ./.;
+      system = "x86_64-linux";
+    };
+  };
+}
+```
+
+Third:
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+  };
+  outputs = { self, nixpkgs }:
+    let
+      system = "x86_64-linux";
+    in
+    {
+      packages.${system}.default = derivation {
+        name = "simple";
+        builder = "${nixpkgs.legacyPackages.${system}.bash}/bin/bash";
+        args = [ "-c" "echo foo > $out" ];
+        src = ./.;
+        system = system;
+      };
+    };
+}
+```
+
+Fourth:
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+  };
+  outputs = { self, nixpkgs }:
+    let
+      name = "simple";
+      system = "x86_64-linux";
+      pkgs = nixpkgs.legacyPackages.${system};
+      src = ./.;
+    in
+    {
+      packages.${system}.default = derivation {
+        inherit name src system;
+        builder = with pkgs; "${bash}/bin/bash";
+        args = [ "-c" "echo foo > $out" ];
+      };
+    };
+}
+```
