+###########
+
+Restoring can occur in either a class::
+
+    class SimpleRestorer(test_capability_capnp.TestSturdyRefObjectId.Restorer):
+
+        def restore(self, ref_id):
+            if ref_id.tag == 'testInterface':
+                return Server(100)

+                raise Exception('Unrecognized ref passed to restore')
+
+    ...
+
+    server = capnp.TwoPartyServer(sock, SimpleRestorer())
+
+Where you inherit from StructType.Restorer, and the argument passed to restore will be cast to the proper type.
+
+Otherwise, restore can be a function::
+
+    def restore(ref_id):
+        if ref_id.as_struct(test_capability_capnp.TestSturdyRefObjectId).tag == 'testInterface':
+            return Server(100)

+
+    ...
+
+    server = capnp.TwoPartyServer(sock, restore)
