 ## Overrides
 
-Use `Container.override()` directly — `modern-di` already ships a first-class
-override mechanism backed by a tree-shared `OverridesRegistry`:
+Use `Container.override()`; overrides are shared across the container tree.
+Generated fixtures resolve during test setup, so apply the override in a fixture
+they depend on. Overriding `di_container` in the test module does that:
 
 ```python
+import typing
+
 import modern_di
+import pytest
 
 from app.ioc import Dependencies
 from app.services import UserService
 from tests.fakes import FakeRepo
 
 
-def test_with_override(
-    di_container: modern_di.Container,

-) -> None:
