Install instructions don't correspond to actual files

[linuxcaffe]

I'm presuming that this hook is still "a thing" and that the discrepancy between the Install part of the README is referring to files that ..used to exist? ..used to be named something else?

cp taskwarrior-shift-all-recurrence-hook/on-* ~/.task/hooks/

is not cromulent as the filenames/folders seem to have changed.
I'm guessing that pirate_add_shift_recurrence.py gets copied as ../on-add_pirate_add_shift_recurrence.py, sort of thing?
