+# protoc-gen-go-grpc
+
+This tool generates Go language bindings of `service`s in protobuf definition
+files for gRPC. For usage information, please see our [quick start
+guide](https://grpc.io/docs/languages/go/quickstart/).
+
+## Future-proofing services
+
+By default, to register services using the methods generated by this tool, the
+service implementations must embed the corresponding
+`Unimplemented<ServiceName>Server` for future compatibility. This is a behavior
+change from the grpc code generator previously included with `protoc-gen-go`.
+To restore this behavior, set the option `require_unimplemented_servers=false`.
+E.g.:
+
+```
+ protoc --go-grpc_out=require_unimplemented_servers=false[,other options...]:. \
+```
+
+Note that this is not recommended, and the option is only provided to restore
+backward compatibility with previously-generated code.

+// The 'go-grpc' suffix becomes part of the argument for the protocol compiler,

+// protoc --go-grpc_out=. path/to/file.proto
+//
+// This generates Go service definitions for the protocol buffer defined by
+// file.proto. With that input, the output will be written to:
