Users on WordPress websites have roles and capabilities.
Cacbots are users on your site, who also have roles and capabilities. The plugin introduces the user role cacbot. In WordPress, users can have multiple roles.
By default, Cacbots have roles cacbot and editor. Upon installation the cacbot can perform any of the actions a WordPress editor can perform. You can adjust this manually, or a Cacbot can modify its own capabilities with an Administrator’s permission.
