If you use CiviCRM and notice something in the documentation that needs correcting or clarifying, you should feel free to update the appropriate wiki page directly. You must sign up for a wiki account and log in in order to edit wiki pages.
Please refer to the Documentation Style Guide for information about formatting and language conventions.
If you are unsure about the changes or you aren't comfortable modifying the documentation for whatever reason, you can contact the maintainer. See the list of Documentation Maintainers.
