This is the oldest Shimano document in this collection. It is a set of instructions for the original Shimano 3.3.3. parallelogram derailleur, with the rather attractive ‘Ninja points’ on its pulley cage.

I like the exploded diagram - but as I don’t understand Japanese, I don’t know whether I like anything else.
