+Set this to a light level beetween 0 and 15. This time is the maximum light level the position may have to allow the first stage go to the second stage. A max_light of 5 means, that a position which receives 0 to 5 light can switch stage, while a position that receives 6 to 15 light cannot.

 ## Usage
 
 This mod can be used in singleplayer and multiplayer. It comes with the canned food items, but no crafting recipes. To get those, install the integration mod for your game. The minetest_game integration is here: [yl_canned_food_mtg](https://gitea.your-land.de/your-land/yl_canned_food_mtg)
