Newbie on Moto X XT1058 (2013)

Hi, I'm completely new to this and would like to try installing this custom OS on my Moto X XT1058 (2013) as I need Android 6 at least. Problem is that I don't know which version would work, if any, and also every guide I've read assumes a previous knowledge that I currently lack so I'm worried about screwing it up.

Help? Please?
