Create a small DokuWiki space with a how-to, an index, attachments, and a page that needs restricted access. Have a colleague find and update the how-to, then check revision history and links after a rename.
A wiki stays useful when content has owners and can be restored. Rehearse a plugin upgrade and backup recovery, especially if authentication depends on another service. Compare how quickly a newcomer finds the correct answer, not just how easily an administrator creates a page.
