Uploading contents of a folder to iCloud Drive

I am a real novice at using iCloud so I hope some kind person can help me with what is probably a simple question!
If I have a folder of documents, (in the specific case I am dealing with they are all pdf's but they could be rtf's) on my Mac running OS X El Capitan 10.11.5 what steps would be in a rule to upload the contents of the folder to iCloud?
At the moment I drag and drop individual documents into a folder in iCloud Drive but hope it can be automated.
Thanks for any help
