-## AWS DAX SDK for Go
+# AWS DAX SDK for Go
 
-AWS DAX SDK for the Go programming language. https://aws.amazon.com/dynamodb/dax
+aws-dax-go is the official AWS DAX SDK for the Go programming language. https://aws.amazon.com/dynamodb/dax
+
+Checkout our [release notes](https://github.com/aws/aws-dax-go/releases) for
+information about the latest bug fixes, updates, and features added to the SDK.
+
+## Getting started
+The best way to get started working with the SDK is to use go get to add the SDK
+to your Go Workspace manually.
+
+    go get github.com/aws/aws-dax-go
+
+You could also use [Dep](https://github.com/golang/dep) to add the SDK to your
+application's dependencies. Using Dep will simplify your update story and help
+your application keep pinned to a specific version of the SDK.
+
+    dep ensure -add github.com/aws/aws-dax-go
+
+## Making API requests
+This example shows how you can use the AWS DAX SDK to make an API request.
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/aws/aws-dax-go/dax"
+	"github.com/aws/aws-sdk-go/aws"
+	"github.com/aws/aws-sdk-go/service/dynamodb"
+)
+
+func main() {
+	cfg := dax.DefaultConfig()
+	cfg.HostPorts = []string{"mycluster.frfx8h.clustercfg.dax.usw2.amazonaws.com:8111"}
+	cfg.Region = "us-west-2"
+	client, err := dax.New(cfg)
+	if err != nil {
+		panic(fmt.Errorf("unable to initialize client %v", err))
+	}
+
+	input := &dynamodb.PutItemInput{
+		TableName: aws.String("TryDaxGoTable"),
+		Item: map[string]*dynamodb.AttributeValue{
+			"pk":    {S: aws.String("mykey")},
+			"sk":    {N: aws.String("0")},
+			"value": {S: aws.String("myvalue")},
+		},
+	}
+
+	output, err := client.PutItem(input)
+	if err != nil {
+		panic(fmt.Errorf("unable to make request %v", err))
+	}
+
+	fmt.Println("Output: ", output)
+}
+```
