Documentation suggestion

What I'm about to say will sound so completely obvious, but I honestly wasted probably 30 minutes figuring it out :P

I just wanted to use brunch to do auto-reloading of static HTML. it wasnt working because I wasn't including app.js as a script in my HTML (because I dont use any javascript). Its completely obvious to me now that you the hot-reloading is done via JS but when it's not working it's just frustrating.

I suggest including an example HTML file which shows including the app.js compiled by brunch in the README
