How to incorporate Google's Web Starter Kit in a Middleman project?

Just found the Google's New Web Starter Kit today and I like it much.

BUT, how would I go about incorporating the baseline HTML, CSS/SASS, JS, etc... into a Middleman project?

I would imagine the answer would also apply to other frameworks like ASP.NET MVC, Ruby on Rails, etc....

Here's the steps I'm doing when incorporating framework to middleman.

• Base HTML, I convert the base HTML to .haml and set this as my layout template.

• Sass, JS, etc, put them in their respective directories (images/, stylesheets/)

Have a look at Bootstrap starter kit for Middleman to give you an idea how to use a framework in Middleman. Hope this helps ;)
