Openlec

okay so I am not sure which one to follow, I have MXIII G going to put openelec on it cause the firmware with this box is glitchy, so I want something more stable. I want to use Kodi like it was meant for and add rocket service to it, So epg.ninja looks promising but the video are confusing. this will be a fresh start so which one to follow guess Jarvis will also be installed. Never used kodi this way. Just want to make sure to follow right steps
go to epg.ninja and follow the directions there. very simple :)
