A bit of time making this more concise and cleaning up the language would go a long way when you get the time. Clarity above all other virtues for documentation, goes doubly for meta-documentation.
The essential advice of all writing: the simplest word choice, the fewest words, is doubly true for technical documentation. Unfortunately only 1% of tech writers seem to follow it.
And as you say, there never seems to be enough time left to document. This is why: a) the doc should be the spec b) write the doc first.
There, that's the concise version of your manifesto :-)
