+minetest_game API
+======================
+GitHub Repo: https://github.com/minetest/minetest_game
+
+Introduction
+------------
+The minetest_game gamemode offers multiple new possibilities in addition to Minetest's built-in API, allowing you to
+add new plants to farming mod, buckets for new liquids, new stairs and custom panes.
+For information on the Minetest API, visit https://github.com/minetest/minetest/blob/master/doc/lua_api.txt
+Please note:
+	[XYZ] refers to a section the Minetest API
+	[#ABC] refers to a section in this document
+	^ Explanation for line above
+
+Bucket API
+----------
+The bucket API allows registering new types of buckets for non-default liquids.
+
+	bucket.register_liquid(
+		"default:lava_source",		-- Source node name
+		"default:lava_flowing",		-- Flowing node name
+		"bucket:bucket_lava",		-- Name to be used for bucket
+		"bucket_lava.png",			-- Bucket texture (for wielditem and inventory_image)
+		"Lava Bucket"				-- Bucket description
+	)
+
+Doors API
+---------
+The doors mod allows modders to register custom doors and trapdoors.
+
+doors.register_door(name, def)
+^ name: "Door name"
+^ def: See [#Door definition]
+ -> Registers new door
+
+doors.register_trapdoor(name, def)
+^ name: "Trapdoor name"
+^ def: See [#Trapdoor definition]
+ -> Registers new trapdoor
+
+#Door definition
+----------------
+{
+	description = "Door description",
+	inventory_image = "mod_door_inv.png",
+	groups = {group = 1},
+	tiles_bottom: [Tile definition],
+	^ the tiles of the bottom part of the door {front, side}
+	tiles_top: [Tile definition],
+	^ the tiles of the bottom part of the door {front, side}
+	node_box_bottom = regular nodebox, see [Node boxes], OPTIONAL,
+	node_box_top = regular nodebox, see [Node boxes], OPTIONAL,
+	selection_box_bottom = regular nodebox, see [Node boxes], OPTIONAL,
+	selection_box_top = regular nodebox, see [Node boxes], OPTIONAL,
+	sound_open_door = sound play for open door, OPTIONAL,
+	sound_close_door = sound play for close door, OPTIONAL,
+	only_placer_can_open = true/false,
+	^ If true, only placer can open the door (locked for others)
+}
+
+#Trapdoor definition
+----------------
+{
+	tile_front = "doors_trapdoor.png",
+	^ the texture for the front and back of the trapdoor
+	tile_side: "doors_trapdoor_side.png",
+	^ the tiles of the four side parts of the trapdoor
+	sound_open = sound to play when opening the trapdoor, OPTIONAL,
+	sound_close = sound to play when closing the trapdoor, OPTIONAL,
+	-> You can add any other node definition properties for minetest.register_node,
+	   such as wield_image, inventory_image, sounds, groups, description, ...
+	   Only node_box, selection_box, tiles, drop, drawtype, paramtype, paramtype2, on_rightclick
+	   will be overwritten by the trapdoor registration function
+}
+
+Farming API
+-----------
+The farming API allows you to easily register plants and hoes.
+
+farming.register_hoe(name, hoe definition)
+ -> Register a new hoe, see [#hoe definition]
+
+farming.register_plant(name, Plant definition)
+ -> Register a new growing plant, see [#Plant definition]
+
+#Hoe Definition
+---------------
+{
+	description = "",	-- Description for tooltip
+	inventory_image = "unknown_item.png",	-- Image to be used as wield- and inventory image
+	max_uses = 30,	-- Uses until destroyed
+	recipe = {	-- Craft recipe
+		{"air", "air", "air"},
+		{"", "group:stick"},
+		{"", "group:stick"},
+	}
+}
+
+#Plant definition
+-----------------
+{
+	description = "",	-- Description of seed item
+	inventory_image = "unknown_item.png",	-- Image to be used as seed's wield- and inventory image
+	steps = 8,	-- How many steps the plant has to grow, until it can be harvested
+	^ Always provide a plant texture for ech step, format: modname_plantname_i.png (i = stepnumber)
+	minlight = 13, -- Minimum light to grow
+	maxlight = default.LIGHT_MAX -- Maximum light to grow
+}
+
+Stairs API
+----------
+The stairs API lets you register stairs and slabs and ensures that they are registered the same way as those
+delivered with minetest_game, to keep them compatible with other mods.
+
+stairs.register_stair(subname, recipeitem, groups, images, description, sounds)
+ -> Registers a stair.
+ -> subname: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
+ -> recipeitem: Item used in the craft recipe, e.g. "default:cobble"
+ -> groups: see [Known damage and digging time defining groups]
+ -> images: see [Tile definition]
+ -> description: used for the description field in the stair's definition
+ -> sounds: see [#Default sounds]
+
+stairs.register_slab(subname, recipeitem, groups, images, description, sounds)
+ -> Registers a slabs
+ -> subname: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
+ -> recipeitem: Item used in the craft recipe, e.g. "default:cobble"
+ -> groups: see [Known damage and digging time defining groups]
+ -> images: see [Tile definition]
+ -> description: used for the description field in the stair's definition
+ -> sounds: see [#Default sounds]
+
+stairs.register_stair_and_slab(subname, recipeitem, groups, images, desc_stair, desc_slab, sounds)
+ -> A wrapper for stairs.register_stair and stairs.register_slab
+ -> Uses almost the same arguments as stairs.register_stair
+ -> desc_stair: Description for stair node
+ -> desc_slab: Description for slab node
+
+Xpanes API
+----------
+Creates panes that automatically connect to each other
+
+xpanes.register_pane(subname, def)
+ -> subname: used for nodename. Result: "xpanes:subname" and "xpanes:subname_{2..15}"
+ -> def: See [#Pane definition]
+
+#Pane definition
+----------------
+{
+	textures = {"texture_Bottom_top", "texture_left_right", "texture_front_back"},
+	^ More tiles aren't supported
+	groups = {group = rating},
+	^ Uses the known node groups, see [Known damage and digging time defining groups]
+	sounds = SoundSpec,
+	^ See [#Default sounds]
+	recipe = {{"","","","","","","","",""}},
+	^ Recipe field only
+}
+
+Default sounds
+--------------
+Sounds inside the default table can be used within the sounds field of node definitions.
+
+default.node_sound_defaults()
+default.node_sound_stone_defaults()
+default.node_sound_dirt_defaults()
+default.node_sound_sand_defaults()
+default.node_sound_wood_defaults()
+default.node_sound_leaves_defaults()
+default.node_sound_glass_defaults()
+
+Default constants
+-----------------
+default.LIGHT_MAX
+^ The maximum light level (see [Node definition] light_source)
+
+Player API
+----------
+The player API can register player models and update the player's appearence
+
+default.player_register_model(name, def)
+^ Register a new model to be used by players.
+ -> name: model filename such as "character.x", "foo.b3d", etc.
+ -> def: See [#Model definition]
+
+default.registered_player_models[name]
+^ Get a model's definition
+ -> see [#Model definition]
+
+default.player_set_model(player, model_name)
+^ Change a player's model
+ -> player: PlayerRef
+ -> model_name: model registered with player_register_model()
+
+default.player_set_animation(player, anim_name [, speed])
+^ Applies an animation to a player
+ -> anim_name: name of the animation.
+ -> speed: frames per second. If nil, default from the model is used
+
+default.player_set_textures(player, textures)
+^ Sets player textures
+ -> player: PlayerRef
+ -> textures: array of textures
+ ^ If <textures> is nil, the default textures from the model def are used
+
+default.player_get_animation(player)
+^ Returns a table containing fields "model", "textures" and "animation".
+^ Any of the fields of the returned table may be nil.
+ -> player: PlayerRef
+
+Model Definition
+----------------
+{
+	animation_speed = 30, -- Default animation speed, in FPS.
+	textures = {"character.png", }, -- Default array of textures.
+	visual_size = {x=1, y=1,}, -- Used to scale the model.
+	animations = {
+		-- <anim_name> = { x=<start_frame>, y=<end_frame>, },
+		foo = { x= 0, y=19, },
+		bar = { x=20, y=39, },
+		-- ...
+	},
+}
+
+Leafdecay
+---------
+To enable leaf decay for a node, add it to the "leafdecay" group.
+
+The rating of the group determines how far from a node in the group "tree"
+the node can be without decaying.
+
+If param2 of the node is ~= 0, the node will always be preserved. Thus, if
+the player places a node of that kind, you will want to set param2=1 or so.
+
+The function default.after_place_leaves can be set as after_place_node of a node
+to set param2 to 1 if the player places the node (should not be used for nodes
+that use param2 otherwise (e.g. facedir)).
+
+If the node is in the leafdecay_drop group then it will always be dropped as an
+item.
+
+Dyes
+----
+To make recipes that will work with any dye ever made by anybody, define
+them based on groups. You can select any group of groups, based on your need for
+amount of colors.
+
+#Color groups
+-------------
+Base color groups:
+- basecolor_white
+- basecolor_grey
+- basecolor_black
+- basecolor_red
+- basecolor_yellow
+- basecolor_green
+- basecolor_cyan
+- basecolor_blue
+- basecolor_magenta
+
+Extended color groups (* = equal to a base color):
+* excolor_white
+- excolor_lightgrey
+* excolor_grey
+- excolor_darkgrey
+* excolor_black
+* excolor_red
+- excolor_orange
+* excolor_yellow
+- excolor_lime
+* excolor_green
+- excolor_aqua
+* excolor_cyan
+- excolor_sky_blue
+* excolor_blue
+- excolor_violet
+* excolor_magenta
+- excolor_red_violet
+
+The whole unifieddyes palette as groups:
+- unicolor_<excolor>
+For the following, no white/grey/black is allowed:
+- unicolor_medium_<excolor>
+- unicolor_dark_<excolor>
+- unicolor_light_<excolor>
+- unicolor_<excolor>_s50
+- unicolor_medium_<excolor>_s50
+- unicolor_dark_<excolor>_s50
+
+Example of one shapeless recipe using a color group:
+minetest.register_craft({
+	type = "shapeless",
+	output = '<mod>:item_yellow',
+	recipe = {'<mod>:item_no_color', 'group:basecolor_yellow'},
+})
+
+#Color lists
+------------
+dye.basecolors
+^ Array containing the names of available base colors
+
+dye.excolors
+^ Array containing the names of the available extended colors
+
+Trees
+-----
+default.grow_tree(pos, is_apple_tree)
+^ Grows a tree or apple tree at pos
+
+default.grow_jungle_tree(pos)
+^ Grows a jungletree at pos
+
+default.grow_pine_tree(pos)
+^ Grows a pinetree at pos
