Personally, I add as much as I can to the notes when publishing a branch. If I learn something when Iβm building, Iβll record a short video for myself or even share as part of a showcase or something.
Iβd like to get to a point where I can automatically document (as much as I can) how components work e.g. capture attributes, their types, variants, etc., so that it means less writing. Iβm not properly documenting anything at the moment, but I should - I moan about this myself in my FT work in Support, so Iβm a hypocrite. π
