 - [Default, without divide](/assets/defaultOutput.md)
 - [With divided Interactor (Input & Output)](/assets/inputOutput.md)
 
+## Depedendency injection
+
+The `createModule` method of `Router` class receives a `ServiceLocator` object as argument. This object provides all the dependencies of the app and will be used to provides dependencies of the module.
+
+In this way, the service locator object is passed between modules. 
+
+An example of ServiceLocator implementation can be found [here](DependencyInjection/ServiceLocatorImpl.swift)
