Because Kodi is open source, there are many developers that create add-ons for the platform. They are divided into two major groups. The ones located in the Official Kodi Addon Repository are official add-ons. All others are unofficial. This add-on is in the second group. You are not allowed to talk about the group 2 add-ons on the official forums or websites. If you need help, you’ll want to contact the developer.
