Documentation improvement

[colorful-tones]

I'm eager to get developing, but do not understand step no. 2 in "Developing with Local" in README:

Run nps components.link in flywheel-local (only needed one time or after unlinking)

Where would this mysterious flywheel-local exist? It is mentioned nowhere in README.

Also, would it be useful to perhaps add the engines field to the package.json? I'm hitting a wall of errors when running yarn storybook, which I suspect is because I'm running an incompatible node/npm version, but cannot be certain.

I'm happy to submit a PR with clarifying text once I'm clear. Thanks!
