 ===============
 Adds the stonecutter block. Used to cut stone like materials into stairs, slabs, etc. Also used as the Stone Mason Villager's jobsite.
 
+### Adding recipes
+
+* To add a new custom stonecutter recipe, use `mcl_stonecutter.register_recipe(input, output, count)`
+* `input` must be a name of a registered item
+* `output` must also be a name of a registered item
+* `count` should be a number denoting output count, this defaults to 1 for `nil` and invalid values
+    * a number with a fraction passed as count will be rounded down
+* Stairs, slabs and walls get their recipes registered automatically
+* Recipe chains are followed automatically, so any recipes taking `output` of another recipe as input will also be taking `input` of that recipe as their input
+
+### Displaying the Stonecutter menu
+
+* To display the stonecutter formspec to a player use `mcl_stonecutter.show_stonecutter_form(player)`
