+We support a feature of auto synchronization, which means that you can easily synchronize all the members of a class by simply calling the `sync_member` function.
 
 We support 4 types of synchronization:
 
 1. Register / Wire type synchronization.
 2. An array (only std::array is supported) of synchronizable objects.
-3. A class which contains only synchronizable objects, and satisfies std::is_aggregate.
-4. A class which has some basis which are synchronizable objects, and has a special tag.
