 Since a ''BlockItem'' for ''SIMPLE_BLOCK'' exists and has been registered, an item model will also be automatically generated that parents the block model. This can be overridden in the ''generateItemModels'' method.
+==== Strict Validation ====
+By default, data generation will throw an exception if the run did not generate blockstates for all blocks belonging to the processed mods.
+Fabric API allows disabling this. To do so, edit your ''build.gradle'' to remove the ''-Dfabric-api.datagen.strict-validation'' VM arg from the ''loom {}'' block.

+FIXME //**This is not done yet!!**//
+==== Addin Data Generation For a Directional Block ====
+**QUICK WARNING**: This is very complicated as heck!!!
+In this, example, we will generate directional blockstates for our ''MACHINE_BLOCK''
+Firstly, we add the block itself and register it!
+<code java>
+// In the Tutorial class (or your mod initializer class)
+public static final Block MACHINE_BLOCK = new Block(FabricBlockSettings.copy(Blocks.BLAST_FURNACE));
+@Override
+public void onInitialize() {
+    Registry.register(Registries.BLOCK, new Identifier("tutorial", "machine"), MACHINE_BLOCK);
+}
+</code>
+Now that we have successfully registered our block, let's get to the good stuff!
+<code java>
+private static class MyModelGenerator extends FabricModelProvider {
+	private MyModelGenerator(FabricDataGenerator generator) {
+		super(generator);
+	}
+	@Override
+	public void generateBlockStateModels(BlockStateModelGenerator blockStateModelGenerator) {
+		// ...
+                blockStateModelGenerator.blockStateCollector.accept(MultipartBlockStateSupplier.create(Tutorial.MACHINE_BLOCK)
+                          .with(When.create().set(Properties.HORIZONTAL_FACING, Direction.NORTH),
+                          BlockStateVariant.create().put(VariantSettings.X, VariantSettings.Rotation.X)));
+	}
+	@Override
+	public void generateItemModels(ItemModelGenerator itemModelGenerator) {
+		// ...
+	}
 }
