What files to copy - Kibble Mod

This is my first Mod. I am trying to restore a bit of game balance by reworking the kibble. I want to have only 3 types of kibble, herbivore, omnivore, carnivore.

These will require similar ingredients with the notable exception of the egg. Any egg will work and the number required depends on the size of the egg.

The carnivore kibble will work with all carnivores, and so on.

Kibble will require the use of the cooking station.

The new kibble will work the same as the old kibble and the old, more specific kibble, will give the dinos a greater stat boost.

Now, I think I have just about all of this figured out. My big question so far is what files should I be copying to my mod folder. I have found no explanation of this and I have seen no pattern to it.
Also, if anyone knows of a problem I’m going to have with any other part of this, that would be helpful too.
