+gRPC Python Client Status Discovery Service package
+===================================================
+
+CSDS is part of the Envoy xDS protocol:
+https://www.envoyproxy.io/docs/envoy/latest/api-v3/service/status/v3/csds.proto.
+It allows the gRPC application to programmatically expose the received traffic
+configuration (xDS resources). Welcome to explore with CLI tool "grpcdebug":
+https://github.com/grpc-ecosystem/grpcdebug.
+
+For any issues or suggestions, please send to https://github.com/grpc/grpc/issues.
