Find out how to install the CIHAutoNox skin with which Kodi?

Hello everyone

In my quest to find a good skin for CinemaScope screens I found this:

Https://github.com/drthaipham/CIHAutoNox

The peculiarity of this skin would be that it automatically detects the format 2.35 or 2.40 etc etc to directly display the correct format. On the link above they say it has been tested with Kodi 16.2 !!!!! Not found

Someone has already tested and if yes how to install it

Thanks in advance

Mike
