+ * Factory-kit is a creational pattern which defines a factory of immutable content
+ * with separated builder and factory interfaces to deal with the problem of
+ * creating one of the objects specified directly in the factory-kit instance.
+ *
+ * <p>
+ * In the given example {@link WeaponFactory} represents the factory-kit, that contains
+ * four {@link Builder}s for creating new objects of
+ * the classes implementing {@link Weapon} interface.
+ * <br>Each of them can be called with {@link WeaponFactory#create(WeaponType)} method, with
+ * an input representing an instance of {@link WeaponType} that needs to
+ * be mapped explicitly with desired class type in the factory instance.
