This entry point of OpenVZ wiki is created in order to arrange all the information on this site more logically. General idea of arrangement is the following. Here you can find something like table of contents. Each chapter contents collection of pages, that pass to the subject of the chapter. Of course there can be articles on the same subject in one chapter: one writes article in own way, another person does it in the other way. It is important, that pages in chapters go in the order of complexity of the material.
It allows the novices at OpenVZ to read only first pages of chapters to start some feature working. Advanced users can quickly go through this table of contents and find more specific information they actually need.
It is greatly appreciated if you will create points in this table (even without writing the article), in order for the community to know what topics are popular and need to be described. Writing articles is also very useful in fact.
