The easiest way to create a conforming Kodi repository is with the create_repository.py tool.
It is documented on the official Kodi Wiki at https://kodi.wiki/view/Add-on_repositories#Repository_Tools.
This Kodi repository contains useful add-ons, including Remote Control Browser, which enables browsing websites with a remote control. An installable repository package is available for download at https://chad.parry.org/software/kodi/.
