+        We need to create a gRPC client for our stub. gRPC provides a with-style helper to
+        manage the lifecycle of the client and its transport so let's use that. We specify the
+        transport to use and configure it appropriately. We're not using TLS so we use
+        the `.plaintext` security transport and specify the server address and port we want to
+        connect to.

-        To make RPCs using the client it needs to be running. Running the client will resolve the
