Each folder and version can have some descriptive text provided for it. This can be done:

• when the document is first added, with
   

  add document
• or later using
   

  add intro
  on the
   

  manage
  menu.

If a document already has some introductory information, amend it using

 

change intro

(to the right of the text).

This information isn't intended for markup and review. It is merely to help people looking at the document understand what it is there for, how it came about and the like. Unlike comments, the information applies to the document, not individual versions.
