This document describes the updating process for the edu-sharing moodle plugin.
Updating the Moodle Plugin is fairly easy:
Just replace the old files of the plugin with the new ones on your server. Next time you log into Moodle it will perform the necessary steps of the update.
If you are updating to version 4.0 make sure to enter "4" in the version-field to enable the new GUI.
Thats it - really
