 Behind the scenes this extension is doing the following for you:
 
 - Automatically resolve the `relay.NodeID` field using the [model's pk](https://docs.djangoproject.com/en/4.2/ref/models/fields/#django.db.models.Field.primary_key)
 - Automatically generate resolves for connections that doesn't define one. For example,
   `some_model_conn` and `some_model_conn_with_total_count` will both define a custom resolver
-  that returns `SomeModel.objects.all()`.
+  automatically that returns `SomeModel.objects.all()`.
 - Integrate connection resolution with all other features available in this lib. For example,
   [filters](filters.md), [ordering](ordering.md) and
   [permissions](permissions.md) can be used together with connections defined
