 ## compiling .proto
 Proto files are stored in /proto. The proto files defined the interface of etcdv3.
-You can compile it like this(if you are running this command inside /proto folder)
-    * $ protoc -I . --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` ./rpc.proto
-    * $ protoc -I . --cpp_out=. ./*.proto
