Wiki

OpenProject offers two different ways to work with project documentation:

Internal wiki – the built-in OpenProject wiki described on this page.
External wiki providers – integrations with external documentation platforms, including XWiki.

This page explains how to use the internal OpenProject wiki.

If you want to connect an external documentation platform such as XWiki to your projects, see the documentation on external wiki providers setup.

Wiki is the built-in OpenProject module for collaboratively creating and editing project documentation. It uses GitHub-flavored CommonMark (GFM) and must be enabled in the project settings before it can be used.

For organizations that prefer to manage documentation outside of OpenProject, external wiki providers such as XWiki can be connected through an integration.

Enable internal wiki

The internal wiki can be enabled for each project individually.

To use the internal wiki, it must first be enabled on your OpenProject instance and then enabled for the project under the project settings.

Editing wiki pages

Wiki pages use the OpenProject WYSIWYG editor, powered by CKEditor 5. The editor supports GitHub-flavored CommonMark (GFM), allowing you to create rich documentation with formatting, images, tables, links, and macros.

Most editing features are available throughout OpenProject. For detailed information about:

The wiki includes additional features that are only available when editing wiki pages.

List of sub-pages – inserts a hierarchical list of all child pages.
