You need some minecraft datapack knowledge, or at least json knowledge. But don't worry, I will cosinder making tutorial.

THIS DATAPACK IS NOT WORKING ITSELF, you have to fill/edit/delete json files
running this datapack without editing will make the mod stop working

!!!!!!!!  DONT FORGET ABOUT "replace": {true/false} in tags and recipe  !!!!!!!!
I've set it to true by default.
Set "replace" to true if you want to CHANGE requirements, set to false if you want to ADD additional requirements.

For fuel, you need to add item both in "#items/respawner_fuel" and "#items/respawner_fuel/{power}". Maximum supported power in single charge is 24.
