+    The ``error_messages`` argument lets you override the default messages that
+    the paginator will raise. Pass in a dictionary with keys matching the error
+    messages you want to override. Available error message keys are:
+    ``invalid_page``, ``min_page``, and ``no_results``.

+
+    .. code-block:: pycon
+
+        >>> from django.core.paginator import Paginator
+        >>> paginator = Paginator([1, 2, 3], 2)
