I am forever tweaking the documentation that accompanies my patterns—hopefully for the better! The changes are usually small; they almost never affect diagrams or notation, and I periodically update the PDFs published on Gumroad, but you can always find the most up-to-date version here.
(It can also be helpful to have the documentation as as separate file, anyway, to more easily refer back to as you work.)
