+12. Enabling `nix-shell`
+
+    In order to use `nix-shell` you need to create a `shell.nix` file:
+
+    ```nix
+    let
+      pkgs = import <nixpkgs> {};
+    in pkgs.callPackage ./default.nix {}
+    ```
+    
+    That will pass the derivations for `stdenv, buildGoPackage, fetchgit, fetchhg, fetchbzr, fetchsvn` into your package derivation. It will use `nixpkgs` (your current channel).
+
 
     After you updated the `default.nix` you can now use `nix-shell`:
