This project uses npm, Browserify, Babeljs, Sass, plus Gnu Make to handle compilation.
Babel & Browserify are handled by npm, but you'll have to install npm, Sass, and
Make for yourself. Install those things, run make in the project's root, and
then get an http server of some description to serve src/demo.html to see
what's going on. I use
http-server for development, and
I find that the command I'm running the most often is:
make clean && make && http-server
