-The `RegistrationFactory`
+The `RegistrationFactory` is a helper class to register interfaces and factories in an `IIocInstaller` and create the needed `IRegistrationBase`s.
+
+## Registering classes
+
+The way classes are registered depends on their `Lifestyle`.
+
+### Register `Transient` classes
+
+To register `Transient` classes, an `IDefaultRegistration<TInterface>` has to be created. The preferred way to do so is to use the generic method `Register<TInterface, TImplementation>()`:
+
+```c#
+RegistrationFactory.Register<IFoo, Foo>();
+```
+
+If for whatever reason you can't use this method, there is also a non generic version of it:
+
+```c#
+RegistrationFactory.Register(typeof(IFoo), typeof(Foo));
+```
+
+### Register `Singleton` classes
+
+To register `Singleton` classes, there has to be a `IDefaultRegistration<TInterface>` created as well. Similar to the registration of `Transient` classes, the preferred way to register `Singleton` classes is to use the generic method `Register<TInterface, TImplementation>()`:
+
+```c#
+RegistrationFactory.Register<IFoo, Foo>(Lifestyle.Singleton);
+```
+
+There is again the possibility to use a non generic version of the method:
+
+```c#
+RegistrationFactory.Register(typeof(IFoo), typeof(Foo), Lifestyle.Singleton);
+```
+
+### Register `Multiton` classes
+
+To register `Multiton` classes, an `IMultitonRegistration<TInterface>` has to be created. The preferred way to do so is to use the generic method `Register<TInterface, TImplementation, TScope>()`:
+
+```c#
+RegistrationFactory.Register<IFoo, Foo, TScope>();
+```
+
+Again there is a non generic method to use:
+
+```c#
+RegistrationFactory.Register(typeof(IFoo), typeof(Foo), typeof(TScope));
+```
+
+## Registering factories
+
+To register abstract factories, an `ITypedFactoryRegistration<TFactory>` has to be created. The preferred way to do so is to use the generic method `RegisterFactory<TFactory>()`:
+
+```c#
+RegistrationFactory.RegisterFactory<IFooFactory>(container);
+```
+
+There is also a non generic version of the method available:
+
+```c#
+RegistrationFactory.RegisterFactory(typeof(IFooFactory), container);
+```
