Oceananigans.jl example needs the simulation data

New to Bonito.jl
When trying the example oceananigans.jl in this REPO I made a folder simulation and looked for the data but could not find it anywhere on the master tree. Please let me know where this is or let me know if I am missing something.
Thanks. 
PS The line 3 "Bernito: styled_slider" gives a warning
"could not import Bonito.styled_slider into Main" but not an error.
