+## Introduction ##
+
 This is a package for GO which can be used to create different types of barcodes.

-* EAN 8
-* EAN 13
+* Code 93
 * Datamatrix
-* QR Codes
-* 2 of 5

+* EAN 8
+* PDF 417
+* QR Code
 
-##Documentation##
+## Example ##
+
+This is a simple example on how to create a QR-Code and write it to a png-file
+```go
+package main
+
+import (
+	"image/png"
+	"os"
+
+	"github.com/boombuler/barcode"
+	"github.com/boombuler/barcode/qr"
+)
+
+func main() {
+	// Create the barcode
+	qrCode, _ := qr.Encode("Hello World", qr.M, qr.Auto)
+
+	// Scale the barcode to 200x200 pixels
+	qrCode, _ = barcode.Scale(qrCode, 200, 200)
+
+	// create the output file
+	file, _ := os.Create("qrcode.png")
+	defer file.Close()
+
+	// encode the barcode as png
+	png.Encode(file, qrCode)
+}
+```
+
+## Documentation ##
 See [GoDoc](https://godoc.org/github.com/boombuler/barcode)
 
 To create a barcode use the Encode function from one of the subpackages.
