A Wiki is an interactive website which can be edited by anyone.
Wikis can be used to create instant virtual communities, and are particularly suited to documentation projects.
If you aren't familiar with the concept of Wikis, a good place to start is here:

There are many different Wiki implementations with differences in their user interfaces, so you should read
About This Wiki.
Most Wikis, and this is no exception, provide a
Sand Box page where you can practice using the Wiki without cluttering up real pages.
