MVC2 Using Unity IoC - How are controllers solved?

Question

I have a question about how the Unity container I installed is resolving controller dependencies. I searched for an explanation of this, but did not find anything that would be clearly visible on this issue. And maybe the answer looks me in the face ... Take a look at the following code, which I am sure many MVC guys have seen:

protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
{
    IController controller;
    try
    {
        controller = container.Resolve(controllerType) as IController;
    }
    catch (Exception ex)
    {
        throw new InvalidOperationException(string.Format("Error resolving controller {0}", controllerType.Name), ex);
    }
    return controller;
}

So this is my redefinition GetControllerInstancein my factory controller that I configured. Obviously, controller types are allowed from a Unity container, but how are they registered in the container in the first place? As you know, the MVC structure registers types in a container? I understand that types are resolved from this container, but I don't like not to know how it resolves controller types.
