+# Abstract Factory
+
+Has primary responsibility for reducing the use of `new`, this pattern provide a interface to create a family objects.
+
+How in example we have a family of Car( Minivan and Pickups ), but can have several implementations how:
+
+- ToyotaFactory
+- GMCFactory
+
+With this pattern we can create any CarFactory, just implemented it.
+
+See follow classes:
+
+- `FactoryCar`
+- `MiniVan`
+- `Pickup`
+- Implementations for `Minivan` and `Pickup`
+- `GMCFactory`
+- `ToyotaFactory`
