[Zope] Add file

Hi, I need to find a way to my users have access to the "Add File" feature. The users do not login. I have them using index_html documents as their way to navigate through the menus. What do I need to do to place "Add File" as a link on the menu. If someone can point me in the right direction or to an example that would be great. Thanks in advance.
