-TODO
+Add the `"use strict";` directive to the top of your files if it is not there
+already.
+
+> This plugin may be enabled via `babel-plugin-transform-es2015-modules-commonjs`.
+> If you wish to disable it you can either turn `strict` off or pass
+> `strictMode: false` as an option to the commonjs transform.
