Tutorial:Custom world generation

Custom world generation is complex and difficult for most data pack or mod creators. To create a more complete world, it is necessary to refer to how the world is generated in the vanilla version.

This tutorial roughly explains some of the vanilla world generation files in 1.20.1, making it easy for creators to read and understand the vanilla world generation.

After 22w42a, most of world generation files can be found in the data/minecraft/worldgen directory in client.jar or server.jar. However, multi-noise biome source parameter list files do not contain details of biome parameter list presets of the vanilla overworld and nether.
