+### GDLib Renderer
+GD library has so many limitations, that GD support is not added as backend, but as separated renderer.
+Use `GDLibRenderer` instead of `ImageRenderer`. These are the limitations:
+
+- Does not support gradient.
+- Does not support any curves, so you QR code is always squared.
+
+Example usage:
+
+```php
+use BaconQrCode\Renderer\GDLibRenderer;
+use BaconQrCode\Writer;
+
+$renderer = new GDLibRenderer(400);
+$writer = new Writer($renderer);
+$writer->writeFile('Hello World!', 'qrcode.png');
+```
