 ## Creational Design Patterns
 
+In plain words:
+
+> Creational patterns are focused towards how to instantiate an object or group
+of related objects.
+
+Wikipedia says:
+
+> In software engineering, creational design patterns are design patterns that
+deal with object creation mechanisms, trying to create objects in a manner
+suitable to the situation. The basic form of object creation could result in
+design problems or added complexity to the design. Creational design patterns
+solve this problem by somehow controlling this object creation.
