+
+## Introduction
+BaconQrCode is a port of QR code portion of the ZXing library. It currently
+only features the encoder part, but could later receive the decoder part as
+well.
+
+As the Reed Solomon codec implementation of the ZXing library performs quite
+slow in PHP, it was exchanged with the implementation by Phil Karn.
+
+
+## Example usage
+```php
+use BaconQrCode\Renderer\ImageRenderer;
+use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
+use BaconQrCode\Renderer\RendererStyle\RendererStyle;
+use BaconQrCode\Writer;
+
+$renderer = new ImageRenderer(
+    new RendererStyle(400),
+    new ImagickImageBackEnd()
+);
+$writer = new Writer($renderer);
+$writer->writeFile('Hello World!', 'qrcode.png');
+```
+
+## Available image renderer back ends
+BaconQrCode comes with multiple back ends for rendering images. Currently included are the following:
+
+- `ImagickImageBackEnd`: renders raster images using the Imagick library
+- `SvgImageBackEnd`: renders SVG files using XMLWriter
+- `EpsImageBackEnd`: renders EPS files
