NPM - How to fix "No readme data"

Simply adding a README.md file will not fix it, you should write something inside it; at least the project title and a brief description is good for people! But for NPM, one byte may be enough...
Doing so should stop showing the warnings.

Also, when you read that warning, ensure that the problem is not related to a 3rd party package.

Just set as private ;)
