Marketo's program cloning is a very powerful tool that enable experts to build comprehensive programs with all what's necessary for other users to clone them and run them.
It would be great if a document or a HTML page could be attached to a program and made clickable in the program summary. It would enable to create a user's guide to the program (for instance what the tokens mean, what to customize in assets, how to create the targets, ...)
My 2 cents
