Unfortunately the Help hasn't been updated to cover this, although it is included in the "Announcements" Forum. However, when in edit mode, click on the "Media" tab and then select "Other Files" from the drop down menu. You can then upload multi-page documents, media (video, etc.) and attach them to one or more persons in your database. If necessary you can also edit the name of the item. Limit of 1Gb space, I think.
