 Where should I put my extensions? / my extensions are not detected

-The extensions register themselves automatically. Just be sure that the python interpreter sees them at least once.
-To that end, we suggest creating a ``PROJECT/schema.py`` file and importing it in your ``PROJECT/__init__.py``
-(same directory as ``settings.py`` and ``urls.py``) with ``import PROJECT.schema``.
+The extensions register themselves automatically. Just be sure that the Python interpreter sees them at least once.
+It is good practice to collect your extensions in ``YOUR_MAIN_APP_NAME/schema.py`` and to import that
+file in your ``YOUR_MAIN_APP_NAME/apps.py``. Performing the import in the ``ready()`` method is the most robust
+approach. It will make sure your environment (e.g. settings) is properly set up prior to loading.
+
+  .. code-block:: python
+
+    # your_main_app_name/apps.py
+    class YourMainAppNameConfig(AppConfig):
+        default_auto_field = "django.db.models.BigAutoField"
+        name = "your_main_app_name"
+
+        def ready(self):
+            import your_main_app_name.schema  # noqa: E402
+
+
+
+While there are certainly other ways of loading your extensions, this is a battle-proven and robust way to do it.
+Generally in Django/DRF, importing stuff in the wrong order often results in weird errors or circular
+import issues, which this approach tries to carefully circumvent.

 My ``@action`` is erroneously paginated or has filter parameters that I do not want
