More Detailed Documentation

[JustCruize]

Hey, recently discovering MaterialUI I think it's a great source and i'd like to use it in my next project.

But I am struggling to get it set up due to the lack of introductory documentation. Apart from the Get Started page on the website and the Example repository, is there anything else I could use to get started that is more detailed?

+1 The CSS could definitely use more docs.
