 # RUN:
 #   start the container:

-#
-#   start nginx:

+#      $ docker run -itp 8080:8080 -p 9091:9091 --name grpc-web grpc-web /bin/bash
+#      $ cd /grpc-web/gConnector && ./nginx.sh
 #
 #   start the grpc server:
 #      docker exec -it grpc-web /grpc-web/net/grpc/gateway/examples/echo/echo_server
+#
+# Once the nginx server and the echo server are both running in different terminals, you
+# can point a web browser to
