Break up the "Increment" paragraph to make it more skimmable.
The paragraph on Increment discusses backlog items completed.
And that it must be "done"
And that the PO decides whether to release.
This would stand out better as three small paragraphs than one big one. The typographical change would help prevent people from missing the point about doneness and the point about release.
The text doesn't need to change other than to break into paragraphs for easier consumption.
