+When you have tested on derecho and are ready to share the new file(s) publically:
+
+As user cesmdata run the rimport script.  This requires a 2FA login, everyone in cseg should have access to the account, you will need to
+contact cislhelp and request access if you are new to the group.
+
+As owner of the files in /glade/campaign/cesm/cesmdata/inputdata run script relink.py, this will remove the files from /glade/campaign/cesm/cesmdata/inputdata
+and replace them with links to the published data location.  /glade/campaign/cesm/cesmdata/inputdata
