# GRPC Client
The grpc client is a [micro.Client](https://godoc.org/github.com/micro/go-micro/client#Client) compatible client.
## Overview
The client makes use of the [google.golang.org/grpc](google.golang.org/grpc) framework for the underlying communication mechanism.
## Usage
Specify the client to your micro service
```go
import (
"github.com/micro/go-micro"
"github.com/micro/go-plugins/client/grpc"
)
func main() {
service := micro.NewService(
micro.Name("greeter"),
micro.Client(grpc.NewClient()),
)
}
```
