What is a wiki?


A wiki (pronounced /ˈwɪki/) is a website that allows the easy[1] creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor.[2][3] Wikis are typically powered by wiki software and are often used to create collaborative websites, to power community websites, for personal note taking, in corporate intranets, and in knowledge management systems.
