### Install the package

<ul><li> If you are using the standard `Go` modules system, import the SDK packages in your code and `go build` will automatically download them. The SDK and its dependencies are modules. </li> <li> Alternatively, you can run the following command: </li></ul>

```shell title={"Shell"} theme={null}
go get github.com/launchdarkly/go-server-sdk/v7

```

### Initialize the SDK

```go title={"Go SDK initialization"} theme={null}
package main

import (
	"fmt"
	"os"
	"time"

	"github.com/launchdarkly/go-sdk-common/v3/ldcontext"
	ld "github.com/launchdarkly/go-server-sdk/v7"
)

func main() {
	ldClient, _ := ld.MakeClient("YOUR_SDK_KEY", 5*time.Second)
	if ldClient.Initialized() {
		fmt.Printf("SDK successfully initialized!")
	} else {
		fmt.Printf("SDK failed to initialize")
		os.Exit(1)
	}

	// For onboarding purposes only we flush events as soon as
	// possible so we quickly detect your connection.
	// You don't have to do this in practice because events are automatically flushed.
	ldClient.Flush()
}

```
