 ## Applying Biome Modifiers
 
 To have NeoForge load a biome modifier JSON file into the game, the file will need to be under `data/<modid>/neoforge/biome_modifier/<path>.json` folder in the mod's resources, or in a [Datapack][datapacks]. Then, once NeoForge loads the biome modifier, it will read its instructions and apply the described modifications to all target biomes when the world is loaded up. Pre-existing biome modifiers from mods can be overridden by datapacks having a new JSON file at the exact same location and name.
 
-The JSON file can be created by hand following the examples in the '[Built-in NeoForge Biome Modifiers](#Built-in-Biome-Modifiers)' section or be datagenned as shown in the '[Datagenning Biome Modifiers](#Datagenning-Biome-Modifiers)' section.
