 __Usage:__ `microexpansion.register_node(<itemstring (string)>, <item definition (table)>`
 
-This API function accepts the same parameters in the definition table as does `minetest.register_craftitem`, however, it makes several modifications to the parameters before passing them on. A new parameter, `usedfor`, is introduced, which if provided is appened on a new line in grey to the item description, a good way to specify what the item does or include more information about it. The `tiles` table is modified so as to simplify the definition when registering the node. Each texture in the `tiles` table has `microexpansion_` added to the beginning and `.png` to the end. This means that rather than specifying something like `microexpansion_chest_top.png`, only `chest_top` is required. __Note:__ the texture path "autocomplete" functionality can be disabled by settings `auto_complete` to `false` in the definition (useful if using textures from another mod). One final extra parameter is `status`, which if set to `no` the description is red, if set to `unstable` the description is `orange`, and if anything else the description is red. The recipe can be automatically registered and defined right in the item definition with the `recipe` table. See `microexpansion.register_recipe` for more information. You can also automatically register ore definitions for the current node with `microexpansion.register_oredef`.
