Can't just say: compute climatology because likely won't know Xarray, and not even Python. Also need to give instructions on how to creating a dummy .py file to run code and print stuff to check on calculations. Would be nice to point them to the documentation of functions you'd want them to use to realize a given calculation, even if in the Zambia case, it would not have helped since they had no internet access, thus no access to documentation. But maybe we can assume this is a very specific case...
