 ### Adding recipes
 
-* To add a new compatible input the item needs to be in the group "stonecuttable".
-* It's output item needs to be in the group "stonecutter_output".
-* "stonecuttable" and "stonecutter_output" need to have the same number.
-* Items like polished granite should only be able to make it's polished variants
-while normal granite can make both. These inputs and outputs need to be in the group 
- "stonecutter_stage".
+* 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
