-The `IRegistrationBase` is an interface that is used to register an interface with the `IocContainer`.
+The `IRegistrationBase` is a base interface for all registration classes that are used to register interfaces with the `IocContainer`.
+
+It consists only of two properties:
+
+```c#
+/// <summary>
+/// The name of the <see cref="IRegistrationBase"/>
+/// </summary>
+string Name { get; }
+```
+
+and

 ## `IDefaultRegistration<TInterface>`
 
+This is the default registration that is used to register a `Type` for the interface it implements. `TInterface` is the `Type` of the interface.
+
+In addition to the implemented properties from the `IRegistrationBase` the `IDefaultRegistration` adds the following properties and methods:
+
+- The Type that implements the `IRegistrationBase.InterfaceType` that gets registered
+  
+  ```c#
+  Type ImplementationType { get; }
+  ```
+
+- The `Lifestyle` of the registered `Type`
+  
+  ```c#
+  Lifestyle Lifestyle { get; }
+  ```
+
+- An `Action` that is invoked when an instance of the registered type is created
+  
+  ```c#
+  Action<TInterface> OnCreateAction { get; }
+  ```
+
+- A method to pass the `OnCreateAction` to the `IDefaultRegistration`
+  
+  ```c#
+  IDefaultRegistration<TInterface> OnCreate(Action<TInterface> action);
+  ```
