+Pretty straightforward - you are provided with the `Type` of each class and
 you can filter by any of the `Type` properties etc. This allows you to

 #### 3. The `AsPublicImplementedInterfaces` method
 
 The `AsPublicImplementedInterfaces` method finds any public, non-nested interfaces 
 (apart from `IDisposable`) that each class implements and registers each
 interface, known as *service type*, against the class, known as the *implementation type*.
+This means if you use an interface in a constructor (or other DI-enabled places)
+then the Microsoft DI resolver will provide an instance of the class that interface
+was linked to.
+*See [Microsoft DI Docs](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-2.1) for more on this*.*
 
 By default it will register the classes as having a lifetime of `ServiceLifetime.Transient`,
 but there is a parameter that allows you to override that.
