-If the class is registered by interface and not by concrete type, you cannot resolve the class by concrete type. Registration of both a concrete type and interface type will resolve different registrations, returning different instances:
+If the class is registered by interface and not by concrete type, you can still resolve the class by concrete type:
 
 ```d

-You can solve this by adding the ADD_CONCRETE_TYPE_REGISTRATION option when registering:
