-### Decorating Structs
+### Using Custom Model Types
 
-Nothing is stopping you from decorating your structs using registered mappers and
-custom decorator models:
+To use a custom model type you simply use the standard `Relation#as` inteface
+but you can pass a constant:
 
 ``` ruby
-class UserStructMapper < ROM::Mapper
-  register_as :ui_presenter
-  model UI::UserPresenter
-end
+class UserRepository < ROM::Repository::Base
+  relations :users, :tasks
 
-user_repo.by_id(1).as(:ui_presenter)
+  def by_id(id)
+    users.by_id(id).as(User)
+  end
+end
 ```

-## Limitations
-
-This is an early alpha and works only with rom-sql for now. There are a couple
-improvements waiting to be done in the rom core and then rom-repository will receive
-more love and features.
-
-Stay tuned.
