 - create a new folder
-- active a new Julia project in this folder 
-- add the `ACEpotentials` package to the folder 
-- From the Julia repl run `using ACEpotentials; ACEpotentials.install_tutorial(@__DIR__())`; this will install `Literate` and `IJulia`, copy the notebook to the current folder in Literate format, then convert it to Jupyter format.
