A wiki is a website that allows for easy editing by multiple authors simultaneously. Wikis are considered to be in a constant state of process, encourage communal and collaborative work, and make it easy to create new pages. They provide a shared open space for building knowledge bases, brainstorming, organizing meetings and notes, and more. Special features of wikis include an "Edit This Page" button, version history, simple formatting, and discussion sections. Wikis can be used for collaboratively writing training manuals, knowledge bases, blogs, and more.
