+QR Code generator
+=================
+
+Master: [![Build Status](https://api.travis-ci.org/Bacon/BaconQrCode.png?branch=master)](http://travis-ci.org/Bacon/BaconQrCode)
+
+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
+$renderer = new \BaconQrCode\Renderer\Image\Png();
+$renderer->setHeight(256);
+$renderer->setWidth(256);
+$writer = new \BaconQrCode\Writer($renderer);
+$writer->writeFile('Hello World!', 'qrcode.png');
+```
