Support for downscaling CMIP6 data

[sdbht]

I am trying to downscale CMIP6 data for my mountainous country Bhutan. I have weather observation data from 1996 to 2016 but it has many missing values and some missing for whole months. I am trying to downscale using your package but somehow I get lost. Do you all have any document that is showing step-wise how to downscale? I eventually want to develop a high-resolution gridded data for Bhutan. I thank for your time and help.
