 ### Creating Ranks
 You can create your own ranks and learn about privilege management in the API documentation. It explains how to manage privileges and register ranks with the `ranks.register` function. Registrations can be made either in the `ranks.lua` file of the mod itself (where default ranks or unregistered), or they can be preferrably placed in a `ranks.lua` file inside the world directory.
 
-If you don't want one of the built in ranks, you can either register a new rank with the same name (effectively overriding the rank) or learn about `ranks.unregister` which can also be called from the world file.
