 ## Factories
 
-Some services require non-trivial construction which means they must be created by a factory class. To do this, create
-a factory class which implements the [Factory](api:SilverStripe\Framework\Injector\Factory) interface. You can then specify
-the `factory` key in the service definition, and the factory service will be used.

+To use any class that not implements Factory interface as a service factory
+specify `factory` and `factory_method` keys.

 ## Dependency overrides
 
 To override the `$dependency` declaration for a class, define the following configuration file.
