 A lot of mods add their own ores, and you'll need a way to place them in existing biomes for players to find. In this tutorial, we'll look at adding ores to existing biomes and biomes added by other mods. There are 2 steps that are required to add ores to biomes. A lot of mods add their own ores, and you'll need a way to place them in existing biomes for players to find. In this tutorial, we'll look at adding ores to existing biomes and biomes added by other mods. There are 2 steps that are required to add ores to biomes.
-  * Iterate over the biome registry to add your ores to existing biomes. +  * Make a ConfiguredFeatures. This defines how your ore block is spawned. 
-  * Use the RegistryEntryAddedCallback to ensure your ore gets added into any biomes added by mods.+  * Use mixin to inject feature registration into DefaultBiomeFeature
  
 We'll assume you've already created your own ore block at this point. Quartz Ore will serve as our replacement, and our goal will be spawning it in overworld biomes. Replace references to Quartz Ore with your ore when appropriate. We'll assume you've already created your own ore block at this point.

-==== Adding ores to a biome ====+==== Making a ConfiguredFeatures ==== 
 +First we need to create a ConfiguredFeatures. Make sure to register your ConfiguredFeature at ''onInitialize''. Feel free to change the values to suit your mod.
  
-First we need to create a method to process a biome, checking if it is a valid biome then adding the ore.+<code java [enable_line_numbers="true"]> 
 +public class ExampleMod implements ModInitializer {

 +      .decorate(Decorator.RANGE.configure(new RangeDecoratorConfig( 
 +        0, // bottom offset 
 +        0, // min y level 
 +        64))) // max y level 
 +      .spreadHorizontally() 
 +      .repeat(20); // number of veins per chunk

-This method adds your ore to the overworld, with the provided spawn settings. Feel free to change the values to suit your mod. +==== Injecting into DefaultBiomeFeature ====

-==== Iterating Biome Registry ==== +

-What we need to do next is process all biomes that have been registered as well as all biomes that will be registered in the future (as added by other mods). We first iterate over the current registry, then register a listener that will be called for future additions.+
