 This package follows a simple dependency-injection pattern. There are two types of components within this pattern. Both are registered in [the Plugin class](/includes/classes/Plugin.php).
 
 1. Modules: Modules are loaded on every execution. They implement the `Module` interface and include a `register` method that performs setup actions. The `register` method is called automatically when the module is instantiated.
-2. Services: Services are loaded when they are declared as dependencies for Modules and other Services. They implement the `Service` interface, but if a service should only be instantiated once and shared throughout the system, it should instead implement the `SharedService` interace.
