# Wiki The *Wiki* tool ![](/files/-LioWHXYa9w0DzZlONES) 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.chamilo.org/1.11.x/teacher-guide/wiki.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
