(schematics documentation) Add more sources

[MonsieurMan]

Hello, I looked over the project because it seemed to me like I could use it for a project I have in mind and couldn't really find a simple dive in introduction.
Until I found the meetup presentation introducing it.
I think it should be added to the head of the readme to help people understand the package as of now, it really helped me understand quickly and I know we're going to use it for at least two projects.

If you know of any information sources you produced like this one I think you should point them out in the head of the readme or something.

Anyway, keep up the good job, I feel like front end development is getting healthier thanks to the trust you and the react community are creating !

@hansl I think you were working on some more Schematics docs, are they available yet?
