+DNS Query Support
+=================
+
+The ``dns.trio.query`` module is for sending messages to DNS servers, and
+processing their responses.  If you want "stub resolver" behavior, then
+you should use the higher level ``dns.trio.resolver`` module; see
+:ref:`trio_resolver`.
+
+There is currently no support for zone transfers or DNS-over-HTTPS
+using Trio, but we hope to offer this in the future.

+The dns.trio.resolver.Resolver Class
+------------------------------------
+
+The Trio resolver is a subclass of ``dns.resolver.Resolver`` and has the
+same attributes.  The methods are similar, but I/O methods like ``resolve()``
+are asynchronous.

+Trio Asynchronous I/O Support
+=============================
+
+The ``dns.trio.query`` module offers very similar APIs to those of
+``dns.query``, only these versions are asynchronous and use Trio for
+I/O.  There are no timeout parameters, as timeouts are expected to be
+done in the Trio style with a cancellation scope.
