  We provide five benchmark hidden valley models with perturbative parton
showers, which span a wide range of dark shower phenomenology. We consider
production through an $s$-channel, heavy mediator, which can be identified with
the SM Higgs. By assuming a set of well-motivated decay portals, one can
moreover fix both the branching ratios of the dark mesons and set a lower bound
on their lifetime. We provide a public python tool which can be used to
generate self-consistent PYTHIA 8 cards for our benchmark models.
