The Wiki has become a great tool for collaborative development of a project's knowledge base.  And the OpenVZ project is making use of this tool in a big way.  The Wiki site is already close to hitting 50 articles, and the content is growing daily.

The Wiki page is filled with fantastic information, covering topics such as Concepts, Technologies, Templates and Kernels, as well as FAQs, Troubleshooting, and HOWTOs just to name a few.

Check it out here.  And login to the site to help out!  Your contributions are welcomed.
