We use npm to manage dependencies. On your first run, run npm install from the root directory of the repo to install dependencies from the npm-shrinkwrap.json file.
We use browserify to generate a single JS file with all of the npm dependencies.
In dev, you can run npm run watch to continually watch for changes and produce an build/bundle.js file.
When you're ready, run npm run compile to produce a minified version of that same file.
