I think this tutorial could be improved by including a repository that shows the directory layout.

I'm familiar with Grunt, but following the step-by-step instructions, I somehow missed wrapping my Gruntfile.js in a module.exports. Maybe complete files would help.

Other than that, this was very helpful! Thank you for putting this together.
