What is a Wiki website?

According to Wikipedia, the world's largest Wiki site:

A Wiki ([ˈwiː.kiː] <wee-kee> or [ˈwɪ.kiː] <wick-ey>) is a type of website that allows users to add, remove, or otherwise edit and change most content. A Wiki enables pages to be written collaboratively, in a simple markup language using a web browser. A single page in a Wiki is referred to as a "Wiki page", while the entire body of pages, which are usually highly interconnected via hyperlinks, is "the Wiki". A Wiki is essentially a database for creating, browsing and searching information.

And that is it! "SA Health Manager Wiki" is a customizable piece of the internet where members can edit content, upload files, communicate and collaborate.
