+	--[[ These biomes try to resemble MC as good as possible. This means especially the floor cover and
+	the type of plants and structures (shapes might differ). The terrain itself will be of course different
+	and depends on the mapgen.
+	Important: MC also takes the terrain into account while MT biomes don't care about the terrain at all
+	(except height).
+	MC has many “M” and “Hills” variants, most of which only differ in terrain compared to their original
+	counterpart.
+	In MT, any biome can occour in any terrain, so these variants are implied and are therefore
+	not explicitly implmented in MCL2. “M” variants are only included if they have another unique feature,
+	such as a different land cover.
+	In MCL2, MC biomes are usually split in two parts: A land part and an ocean part. Sometimes there's a beach/shore part as well.
+
+	The ocean biomes correspond to the MC Ocean biome.
+
+	Other intentionally missing biomes:
+	* River (generated by valleys and v7)
+	* Plateau (pure terrain)
+
+	Tricky are the beach (esp. stone beach) and mushroom island biomes as they have specific conditions we can't check in MT. :(
+	TODO: Find a way to position these biomes accordingly.
+
+	Biomes TODO list:
+	* Savanna M (coarse dirt instead of dirt)
+	* Jungle Edge M (super rare but melons are common here)
+	* Mesa biomes
