-Canned fruits/vegetables, and jams for Minetest game
+# Canned Food
+
+This mod introduces a variety of canned foods to add some pleasant variety into the available
+assrtment of foods and item uses. It relies on the glass bottle from the default vessels mod,
+giving this otherwise little used item a considerable purpose.
+
+All products are defined by shapless recipes, and yield items which can be placed in the
+real world. Although the cans with non-symmetrical items on labels look good only from
+half of the angles.
+
+The recipes follow the scheme of "glass bottle" + "produce" [ + "sugar" ]
+
+The default 4 items do not require sugar, even though 3 of those are jams and probably 
+would taste horribly IRL without sugar:
+* Apple jam
+* Canned brown mushrooms
+* Rose petal jam
+* Dandelion jam
+
+This is to guarantee that they will always be available in vanilla game. As you can notice,
+canning also turns two othwerise inedible objects into food.
+
+Ethereal and farming (redo) mods introduce items that can be canned, too. 
+Some of them (jams) require sugar as the third ingredient. So some of them require both mods.
+
+The mason jars with canned food can be put into vessel storage shelves. Or put on display 
+just like the glass vessels can, and destroyed by hand (retreiving the item).
+
+The benefit of canning the food is higher nutritional value (since shelf life is irrelevant
+in minetest game, where food never goes bad), this is a "reward" for going through effort
+to obtain the glass vessels. When the contents of the jasr are consumed, 
+the player is left with an empty glass bottle which can be reused.
