Item Descriptions

JEI supports adding descriptions for items so players can easily learn what an items does. To add a description, inside of your plugin's registerRecipes() function, call IRecipeRegistration.addIngredientInfo(ItemStack item, IIngredientType type, Component... description). Note that in this case, type is the type of ingredient. If you haven't added your own type, this should either be VanillaTypes.ITEM_STACK or ForgeTypes.FLUID.
