 The following snippet shows how to query the state using gRPC inside a Go program. The idea is to create a gRPC connection, and use the Protobuf-generated client code to query the gRPC server.
 
+#### Install cosmos sdk

+Add below line to `go.mod` to replace protobuf, read more [#8469](https://github.com/cosmos/cosmos-sdk/issues/8469)
