+## Extending this mod (naming conventions)
+If you want to extend this mod with your own functionality, it is recommended
+that you put all API functions into `doc.sub.<name>`.
+As a naming convention, if your mod depends on `doc`, your mod name should also start
+with “`doc_`”, like `doc_items`, `doc_minetest_game`, `doc_identifier`.
+
+One mod which uses this convention is `doc_items` which uses the `doc.sub.items`
+table.
