I just ran into an issue with the way they blog their documentation. It isn't hierarchical from what I can tell and they don't go back and update blogs to point you at the latest document. I wasted a lot of time going step-by-step through one to find out it was deprecated.
It is a problem because a lot of the good documentation about overall usage or architecture for some reason is in this blog format but I can see it just being written off because "its just a blog".
They also leave a lot out of the true documentation such as Landing Zone stuff (in fact they hide this one entirely) and Application Discovery Service (they make no mention how the agents work). There are plenty of other minutia that I have had to contact our rep. to get from the product team.
The most common or basic stuff has some great documentation. But once you stray into the "weird" it isn't uncommon to see 2 or 3 line documentation pages about something.
