+### `recipe_data(item, type?)`, `recipe_data(recipe, type?)`
+
+returns all recipes matching either an `item`, or represent actual `recipe` name. In vanilla datapack, for all items
+that have one recipe available, the recipe name is the same as the item name but if an item has multiple recipes, its
+direct name can be different.
+
+Recipe type can take one of the following options:
+ * `'crafting'` - default, crafting table recipe
+ * `'smelting'` - furnace recipe
+ * `'blasting'` - blast furnace recipe
+ * `'smoking'` - smoker recipe
+ * `'campfire_cooking'` - campfire recipe
+ * `'stonecutting'` - stonecutter recipe
+ 
+ The return value is a list of available recipes (even if there is only one recipe available). Each recipe contains of
+ an item triple of the crafting result, list of ingredients, each containing a list of possible variants of the
+ ingredients in this slot, as item triples, or `null` if its a shaped recipe and a given slot in the patterns is left
+ empty, and recipe specification as another list. Possible recipe specs is:
+  * `['shaped', width, height]` - shaped crafting. `width` and `height` can be 1, 2 or 3.
+  * `['shapeless']` - shapeless crafting
+  * `['smelting', duration, xp]` - smelting/cooking recipes
+  * `['cutting']` - stonecutter recipe
+  * `['special']` - special crafting recipe, typically not present in the crafting menu
+  * `['custom']` - other recipe types
+  
+Note that ingredients are specified as tripes, with count and nbt information. Currently all recipes require always one
+of the ingredients, and for some recipes, even if the nbt data for the ingredient is specified (e.g. `dispenser`), it
+can accept items of any tags.
+
+Also note that some recipes leave some products in the crafting window, and these can be determined using
+ `crafting_remaining_item()` function 
+  
+ Examples:
+ <pre>
+ recipe_data('iron_ingot_from_nuggets')
+ recipe_data('iron_ingot')
+ recipe_data('glass', 'smelting')
+ </pre>
+
+### `crafting_remaining_item(item)`
+
+returns `null` if the item has no remaining item in the crafting window when used as a crafting ingredient, or an
+item name that serves as a replacement after crafting is done. Currently it can only be buckets and glass bottles.
+
 ### `inventory_size(inventory)`
 
 Returns the size of the inventory for the entity or block in question. Returns null if the block or entity don't
