[Zope-CMF] how to setup plone collector and wiki in plone?

[Wostenberg]

What are basic steps to adding collector and zwiki to a plone site? I've 
added regular zwiki and trackers products to Zope sites in past, but it 
looks like adding to a Plone site is different.

If an expert steps up with a cookbook I'll transcribe answer to 
http://plone.org/documentation/UnansweredQuestions "how do I add 
collector" for posterity.
