+Dubbo-go has supported many RPC protocols, like Triple, Dubbo JSONRPC, gRPC, HTTP, HTTP2.
 
 - Triple is the supported protocol of Dubbo3 ecology, and is gRPC extended protocol based on HTTP2, which is compatible with gRPC service.In other words, **on the basis of gRPC's reliable invocation, it adds Dubbo's service governance capability.**
-- Dubbo protocol  is tradition Dubbo ecology protocol, which is capitable with dubbo 2.x, and is a good choice for cross-language invocation between GO and Java old service.
+- Dubbo protocol is tradition Dubbo ecology protocol, which is compatible with Dubbo 2.x, and is a good choice for cross-language invocation between GO and Java legacy service.
 - HTTP support：As you can see in the figure above, you can invoke Triple/Dubbo service using HTTP protocol through [dubbo-go-pixiu](https://github.com/apache/dubbo-go-pixiu) gateway.
