 ## Are you a mod developer?

 Does one of your mods add new tools?
-If so, to support this mod, check if it is loaded with
+If so, to support this mod, add this code to your mod, after your tool's code:
-```minetest.get_modpath("toolranks")```
+
-and then replace all after_use definitions with toolranks.new_afteruse.
+```lua
-Optionaly, you can also replace tools description with
+if minetest.get_modpath("toolranks") then
-```toolranks.create_description("Tool Name", 0, 1)```
+    minetest.override_item("mymod:mytool", {
-and then set original_description to your tools name.
+        original_description = "My Tool",
+        description = toolranks.create_description("My Tool", 0, 1),
+        after_use = toolranks.new_afteruse

+Or alternatively, you can use the helper function:
+
+```lua
+toolranks.add_tool("mymod:mytool")
