 This API allows you to add more walls (like the cobblestone wall) to MineClone 2.
 
-## `mcl_walls.register_wall(nodename, description, tiles, invtex, groups, sounds)`
+## `mcl_walls.register_wall(nodename, description, craft_material, tiles, invtex, groups, sounds)`
 
 Adds a new wall type. This is optimized for stone-based walls, but other materials are theoretically possible, too.
 
 The current implementation registers a couple of nodes for the different nodeboxes.
 All walls connect to solid nodes and all other wall nodes.
 
-The crafting recipe is NOT registered, you have to add your own.
+If `craft_material` is not `nil` it also adds a crafting recipe of the following form:
+
+    CCC
+    CCC
+    
+    Yields 6 walls
+    C = craft_material (can be group)
 
 ### Parameters
 * `nodename`: Full itemstring of the new wall node (base node only). ***Must not have an underscore!***
 * `description`: Item description of item (tooltip), visible to user
+* `craft_material`: Item to be used in the crafting recipe. If `nil`, no crafting recipe will be added
 * `tiles`: Wall textures table, same syntax as for `minetest.register_node`
 * `inventory_image`: Inventory image (optional, default is an ugly 3D image)
 * `groups`: Base group memberships (optional, default is `{cracky=3}`)
