To begin using do the following.
git clone git@github.com:veg/veg-hiv-env.git
cd veg-hiv-env
bower install
Then open test.html in a browser. Note that this may not work in some browsers, e.g. Chrome because of how it implements the same origin policy for file:/// URLS; in this case put the directory in somewhere that can be accessed by HTTP.
You need to have the bower package manager installed (which itself needs npm).
