To utilize the mod, a player must hold the brush in their main hand and a biome paint in their off-hand, or vice versa. The mod is compatible with other mods, but currently only offers recipes for vanilla biome paints. The creator notes that this can be extended with a data pack. The use of Just Enough Items (JEI) is recommended for viewing the paint recipes.
