Add Description to Folder

[Elvis72]

I am in the All Documents View and I have a list of folders that hold procedures.

The name of the folder has the procedure number, but we need to also add the title for reference.

I added the Description column to the view, and I see it...but I cannot for the life of me figure out how to add the individual text to each folder.

Name Description
FC-OP-ROU-07001 Respond to Ammonia Contamination

Thanks!~
