-            The object manager uses mappings to determine what the default implementation is for a class in a constructor (scope dependent).
-            For this goal where designed preference node in the di.xml settings file.
-            For example:
-            In class A here are dependencies in the constructor - interface B and class C.
-            Our aim to get in the class A concrete realization of interface B - BConcrete and replace concrete implementation for class C on its child CSpecific.
-            We can easily determine for object manager to instantiate interface B as concrete class BConcrete by using this template.
-            In the same way, we can determine for object manager to instantiate class CSpecific instead of class C.
+            The object manager uses abstraction-implementation mappings when the constructor signature of a class requests
+            an object by its interface. The object manager uses these mappings to determine what the default implementation
+            is for that class for a particular scope.
