 ## API
 
 The plugin is packed with a rich API for interacting with chunk loaders and more. When hooking into the plugin, it's highly recommended to only use the API and not the compiled plugin, as the API methods are not only commented, but also will not get removed or changed unless they are marked as deprecated. This means that when using the API, you won't have to do any additional changes to your code between updates.
