This data pack requires a resource pack. The resource pack can be found in the downloaded .zip file.

A festive Christmas data pack adding Christmas-themed decorations.
This data pack is still in beta, so there will be more features and improvements in the future.

To install, simply drag all files in the downloaded .zip file into your world folder.
Alternatively, you can put resources.zip into your resourcepacks folder and apply it there.

Getting started with the data pack:

To make a recipe book, throw a book and a spruce sapling onto your Christmas Crafter

You can find pine trees and mistletoes in chests in spruce villages. You can find pine trees in chests in snowy villages as well.
