#
# 1. In any directory, create 'Tables/', 'Test/' and 'CMIP6/' directories.
#
# 2. Download
# https://github.com/PCMDI/cmor/blob/master/TestTables/CMIP6_Omon.json
# and https://github.com/PCMDI/cmor/blob/master/TestTables/CMIP6_CV.json
# to the 'Tables/' directory.
#
# 3. Download
# https://github.com/PCMDI/cmor/blob/master/Test/<filename>.json
# to the 'Test/' directory.
