 ## Overview
 
-Polyglot solutions of clients for [Apache RocketMQ](https://rocketmq.apache.org/), and both of them follow the specification of [rocketmq-apis](https://github.com/apache/rocketmq-apis), replace the previous protocol based on `RemotingCommand` by [Protocol Buffers](https://developers.google.com/protocol-buffers) and [gRPC](https://grpc.io/). Apart from that, APIs from clients of different languages share the same model and semantics.
+Client bindings for [Apache RocketMQ](https://rocketmq.apache.org/), all of them follow the specification of [rocketmq-apis](https://github.com/apache/rocketmq-apis), replacing 4.x remoting-based counterparts. Clients in this repository are built on top of [Protocol Buffers](https://developers.google.com/protocol-buffers) and [gRPC](https://grpc.io/).
 
 ## Goal
 
-Provides cloud-native and robust solutions for mainstream programming languages.
+Provide cloud-native and robust solutions for Java, C++, C#, Golang, Rust and all other mainstream programming languages.
