THIS ADD-ON IS ONLY FOR PEOPLE WHO HAVE THEIR OWN M3U LIST SO THEY CAN ADD IT TO THE IPTV CLIENT TO WATCH CHANNELS.
Select TV (or Live TV if you are on a version lower than 15.2 and if you are then consider updating)
You will now see a pop-up saying that you have no PVR Client enabled. Select OK
Scroll down and select PVR IPTV Simple Client
In General select M3U Play List URL
Add your M3U URL into the address section
Select OK again
On your Home Screen you should now see TV (or Live TV if on an older version of Kodi). Open that to see the live channel list
The list should look like this. Select a channel for it to load and play
The PVR Simple Client should now be setup with live tv streams available.
