+# mkShell
+
+pkgs.mkShell is a special kind of derivation that is only useful when using
+it combined with nix-shell. It will in fact fail to instantiate when invoked
+with nix-build.
+
+## Usage
+
+```nix
+{ pkgs ? import <nixpkgs> {} }:
+pkgs.mkShell {
+  # this will make all the build inputs from hello and gnutar available to the shell environment
+  inputsFrom = with pkgs; [ hello gnutar ];
+  buildInputs = [ pkgs.gnumake ];
+}
+```
