 # Lightstep OpenTelemetry Golang Exporter
 
-This is a Lightstep exporter for opentelemetry-go.
-
-## Initialize
-
-This example connects to Lightstep and sends a single span.
-
-```go
-package main
-
-import (
-	"context"
-	"log"
-
-	"github.com/lightstep/opentelemetry-exporter-go/lightstep"
-	"go.opentelemetry.io/otel/api/global"
-	sdktrace "go.opentelemetry.io/otel/sdk/trace"
-)
-
-func main() {
-	exporter, err := lightstep.NewExporter(
-		lightstep.WithAccessToken("<ACCESS_TOKEN>"),
-		lightstep.WithServiceName("my-service"),
-	)
-	if err != nil {
-		log.Fatalf("Failed to initialize Lightstep exporter: %v", err)
-	}
-	defer exporter.Close()
-
-	tp, err := sdktrace.NewProvider(
-		sdktrace.WithConfig(sdktrace.Config{
-			DefaultSampler: sdktrace.AlwaysSample()}),
-		sdktrace.WithSyncer(exporter))
-	global.SetTraceProvider(tp)
-
-	ctx := context.Background()
-	_, span := global.Tracer("example").Start(ctx, "hello")
-	span.End()
-
-	exporter.Flush()
