About Wikis and XWiki
Explanation
What is a wiki?
A wiki is a collaborative platform where anyone can create, edit and organize content. On top of that, most wikis add access rights management and notifications.
That flexibility covers a wide range of situations:
- Share knowledge: build a knowledge base, a product catalog or documentation.
- Manage projects: organize events, develop products or set up new tools.
- Collaborate and communicate: run a website, an intranet or an extranet for your team.
A wiki is, in short, the central place where a team's information is stored and stays accessible to everyone who needs it.
What makes XWiki special?
XWiki is a second generation wiki: besides writing Pages together, you can turn those Pages into applications, such as a FAQ, a task list or a set of product sheets, without programming.

Four ways XWiki is used, clockwise from top left: as a website, as a collaborative knowledge base, as a collaborative intranet, and as a public wiki and learning platform.
See Projects Powered by XWiki for what other teams have built.
