Installing add-ons

Warning: Please be aware that some contributed modules and plugins have not been reviewed, and the quality and/or suitability for your Moodle site has not been checked. The modules and plugins may have security problems, data-loss problems, interface problems or just plain not work. Please think carefully about maintenance before relying on contributed code in your production site, as some of this code may not work with future versions of Moodle.
