+=====================
+
+This file provides information about the API of unified_inventory.
+
+
+Misc functions
+--------------
+Grouped by use-case, afterwards sorted alphabetically.
+
+* `unified_inventory.is_creative(name)`
+	* Checks whether creative is enabled or the player has `creative`
+
+
+Pages
+-----
+
+Register a new page: The callback inside this function is called on user input.
+
+	unified_inventory.register_page("pagename", {
+		get_formspec = function(player)
+			-- ^ `player` is an `ObjectRef`
+			-- Compute the formspec string here

+				formspec_prepend = false, -- default `false`
+				-- ^ Optional. When `false`: Disables the formspec prepend
+			}
+		end,

+
+
+Buttons
+-------
+
+Register a new button for the bottom row:
+
+	unified_inventory.register_button("skins", {
+		type = "image",
+		image = "skins_skin_button.png",
+		tooltip = "Skins",
+		hide_lite = true
+		-- ^ Button is hidden when following two conditions are met:
+		--   Configuration line `unified_inventory_lite = true`
+		--   Player does not have the privilege `ui_full`

+
