Adding Credits
If you want to add credits to your mod, there are 2 ways of doing so: Overriding, or Appending.
Overriding
If you want to override the credits text file
then you just have to create a text file named credits
in the data directory of your mod.
Appending
If you want to append credits to the game's credits,
then in the _append/data folder
you'll wanna create a text file named credits.
After
and then after you do either one of those you're done!
