I like it too, thanks to both of you!

I have two small ideas for improvement: 
- Swap the first two paragraphs. First say what it is, and then give the 
motivation.
- The section about the descriptor protocol is a bit difficult to 
understand. But judging from the official descriptor documentation, it seems 
to be hard to explain: The official documentation is nearly incomprehensible 
(IMHO).
