How do I make a basic Game.ini mechanics adjustment into a mod like Epic Level?

I am still looking for help on this. I adjusted my code to support the additional 15 levels unlocked in Aberration, and it all continues to work fine in my single player game but I would still like to make it into a mod so I can share it with people. Epic Levels, Difficulty (the countless renditions of), Annunaki, and many other mods all adjust the same settings that I am adjusting. My ARK Dev Kit is up to date.

How do I make a mod that changes levels, stats/point, difficulty, and stuff? Isn’t there a guide somewhere? I’ve read a few threads but they were all out of date and unhelpful and there are countless threads and I don’t want to spend the rest of my life reading them all just so I can make one mod to apply something I’ve already coded.
