About this project
What does D Version add?

This mod adds most of the content from other versions. For example, if you want to play on 1.21.4, but the mod only supports up to 1.21.1, then you just download my mod — it adds part of the features that were introduced in 1.21.4, such as the new biome.
How to install the mod correctly?
Go to the “Versions” section — there you’ll see something like (version in version).
The first version is the one that adds content to your world,
and the second version is the version of the game you need to install the mod on.
