+Minetest mod: Hunger [hbhunger]
+===============================
+Version: 0.3.0
+
+License of source code: WTFPL
+-----------------------------
+by Wuzzy (2015)
+
+Forked from the “Better HUD (and hunger)” mod by BlockMen (2013-2014).
+
+
+Using the mod:
+--------------
+This mod adds a mechanic for hunger.
+This mod depends on the HUD bars mod [hudbars], major version 1.
+
+You can create a "hunger.conf" file to customize the properties of hunger for your needs.
+
+About hunger
+============
+This mod adds a hunger mechanic to the game.
+A new player starts with 20 satiation points out of 30.
+Player actions like digging, placing and walking cause exhausion, which lower the player's
+satiation. Also every 800 seconds you lose 1 satiation point without doing anything.
+If you are hungry (0 satiation) you will suffer damage and die in case you don't eat something.
+If your satiation is greater than 15, you will slowly regenerate health points.
+Eating food will increase your satiation.
+Important: Eating food will not directly increase your health anymore, as long as the food item
+is supported by this mod (see below).
+
+
+Currently supported food:
+-------------------------
+- Apples (default)
+- Animalmaterials (mobf modpack)
+- Bread (default)
+- Bushes
+- bushes_classic
+- Creatures
+- Dwarves (beer and such)
+- Docfarming
+- Fishing
+- Farming plus
+- Farming (default and Tenplus1's fork)
+- Food
+- fruit
+- Glooptest
+- JKMod
+- kpgmobs
+- Mobfcooking
+- Mooretrees
+- Mtfoods
+- mushroom
+- mush45
+- Seaplants (sea)
+- Simple mobs
+
+Examples: 
+Eating an apple (from the default Minetest game) increases your satiation by 2,
+eating a bread (from the default Minetest game) increases your satiation by 4.
