# Wiki

The *Wiki* tool ![](https://748165138-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LH9CCYPqjHw1VKNcuiq%2F-LioVXsO8I_YmhlcnGyg%2F-LioWHXYa9w0DzZlONES%2Fgraphics208.png?generation=1562101775930288\&alt=media) is a collective or collaborative redaction tool. It allows users to work together on a single document, and to follow the history of modifications. It also allows you to save time and be more efficient during a group task. In many ways, it complements the forum tool.

A wiki page can contain many links to other pages, which may or may not (yet) have existing content. Wiki pages can be updated; each contributor sharing the same rights to write and edit content. Originally designed to support collaboration between learners, the wiki may, at the beginning of a course, consist only of a list of links inserted by the teacher, pointing to empty pages which each learner will have to build using one another's ideas, views and experiences.
