-====== Creating a Dimension [WIP] ======
+====== Minecraft 1.16 and later ======
+The information below applies to Minecraft 1.15 and earlier, while in Minecraft 1.16, dimensions can be defined in data packs. More information about custom dimensions in 1.16 can be found in the [[https://minecraft.fandom.com/wiki/Custom_dimension|official wiki]].
+However, you must still create a portal using fabric, [[tutorial:custom_portals|more information about custom portals here.]]
+An example that also shows some of the fabric-api specific code can be found in the [[https://github.com/FabricMC/fabric/tree/1.16/fabric-dimensions-v1/src/testmod|fabric-dimensions-v1 testmod]].
+====== Creating a Dimension [WIP] (1.15 and earlier) ======
 Creating your own dimension is an advanced topic. This tutorial assumes you have already read through the previous tutorials on world generation, and have other basic knowledge such as how to create your own blocks.

-The ''defaultPlacer'' determines the default placement when an entity is teleported into this dimension. Here we have made it so the entity spawns on the top block at 0, 0 when entering the dimension. If you want custom portal logic, this is the place to do it. See the [[https://github.com/FabricMC/fabric/blob/1.15/fabric-dimensions-v1/src/main/java/net/fabricmc/fabric/api/dimension/v1/EntityPlacer.java|EntityPlacer documentation]] for details.
