Documentation on upgrading to Domino 9

The documentation on upgrading to Domino 9 is a veritable wasteland.
- hardware requirements are terribly out of date.
- The so called "step-by-step installation instructions" are far from it.
It basically points to the 8.5 Domino infocenter.
- The "Domino for IBM i: Getting Started" points to an ancient document
about 8.5 which basically says this wasn't updated even for 8.5 use the
8.0 edition.
- There's a wiki which recommends you perform maintenance on a list of
databases after the upgrade but before starting the server. One person
responded to that wiki with basically "what, pray tell, maintenance would
you like us to perform?".

Is there some real documentation someplace?

Is there a wiki someplace we can update ourselves without waiting for IBM
approval?
