More guidance on how to make samples work #111

Right now I wished to try the ray tracer sample. I've little experience with most of the web stuff here outside of basic ES6 javascript and html. I've cloned the whole repo and opened the folder in VS Code.

However, I can't locate a means of running the sample I want or setting up the dependencies. I found some instructions in Browserify but I'm missing package.json on the second step.

This tells me I've clearly missed some fundamental basics but there is nothing indicating how to go from minimal knowledge to making these run.

Help?
