I think we should almost always start a topic by expanding on or defining the concept in the title.

The para you wrote is good, broad info, but doesn't anchor the user. We had a lot of paras like this in the older documentation where we started out too broad. As a reader, I often found it hard to find the "nut" of the paragraph.

I think the broad to the narrow doesn't necessarily have to be in perfect sequence. I'd anchor the user, then give background.
