I copied & pasted the example code from readme

```auto
package dgraph

import (
	"log"
	"google.golang.org/grpc"
	"github.com/dgraph-io/dgo"
	"github.com/dgraph-io/dgo/protos/api"
	"context"
)

func F() error {
	conn, err := grpc.Dial("localhost:5080", grpc.WithInsecure())
	if err != nil {
		log.Fatal(err)
	}
	defer conn.Close()
	dgraphClient := dgo.NewDgraphClient(api.NewDgraphClient(conn))

	op := &api.Operation{
		Schema: `name: string @index(exact) .`,
	}
	err = dgraphClient.Alter(context.Background(), op)
	return err
}

```

get

```auto
rpc error: code = Unimplemented desc = unknown service api.Dgraph

```

You are connecting to the wrong port. It should be 9080.
