+========================================================
+How to configure event loop factories from the test item
+========================================================
+
+``pytest_asyncio_loop_factories`` is called with the current pytest ``item``.
+Use that item to decide which named event loop factories are available for the test being collected.
+
+For example, a hook can inspect the test's fixtures and return a different factory mapping for tests that request a particular fixture.
+In ``conftest.py``, check the current item's fixture names and build the factory mapping for that item:
+
+.. include:: configure_loop_factories_per_test/conftest.py
+   :code: python
+
+Then request the fixture from tests that should use the custom factory:
+
+.. include:: configure_loop_factories_per_test/test_extra_loop_factories.py
+   :code: python
+
+In this example, ``test_runs_with_default_factory_only`` is parametrized only over ``default``, while ``test_runs_with_custom_factory_only`` is parametrized only over ``custom``.
+
+The same pattern works with any information available from the current pytest item, such as fixture names, markers, node IDs, or file paths.
+
+Because this is a standard pytest hook, its placement also matters.
+An implementation in a nested ``conftest.py`` applies to tests collected under that directory.
+Use this when a whole package or directory should share the same factory set.
+
+For declaring factories without item-specific logic, see :doc:`custom_loop_factory`.
+
+For selecting a subset of available factories from a test, see :doc:`run_test_with_specific_loop_factories`.

 How to run a test with specific event loop factories only
 =========================================================
 
-To run a test with only a subset of configured factories, use the ``loop_factories`` argument of ``pytest.mark.asyncio``:
+``pytest_asyncio_loop_factories`` determines which named event loop factories are available for each test item.
+By default, pytest-asyncio parametrizes a test with every factory returned for that item.
+Use ``loop_factories`` to select a subset of the factory names returned by the hook.
 
-.. code-block:: python
+Assume ``conftest.py`` provides two named factories:
 
-   import pytest
+.. include:: run_test_with_specific_loop_factories/conftest.py
+   :code: python
 
+Then use ``loop_factories`` to select which available factory names a test should run with:
 
-   @pytest.mark.asyncio(loop_factories=["custom"])
-   async def test_only_with_custom_event_loop():
-       pass
+.. include:: run_test_with_specific_loop_factories/test_loop_factories_subset.py
+   :code: python
 
 If a requested factory name is not available from the hook, the test variant for that factory is skipped.
+
+For declaring the factories themselves, see :doc:`custom_loop_factory`.
+
+For choosing the available factories from the pytest item, see :doc:`configure_loop_factories_per_test`.
