+    Each non-abstract :class:`~django.db.models.Model` class must have a
+    :class:`~django.db.models.Manager` instance added to it.
+    Django ensures that in your model class you have  at least a
+    default ``Manager`` specified. If you don't add your own ``Manager``,
+    Django will add an attribute ``objects`` containing default
+    :class:`~django.db.models.Manager` instance. If you add your own
+    :class:`~django.db.models.Manager` instance attribute, the default one does
+    not appear. Consider the following example::
+
+        from django.db import models
+
+        class Person(models.Model):
+            # Add manager with another name
+            people = models.Manager()
+
+    For more details on model managers see :doc:`Managers </topics/db/managers>`
