+# OnlyQR - SVG QR Code Generator
+
+A simplified, SVG-only QR code generator based on QRCode.js. This lightweight library generates clean, scalable SVG QR.
+
+Try it out at [OnlyQR Demo](https://onlyqr.0n8.de).
+
+## Changes from Original QRCode.js
+
+- Removed Canvas and Table rendering methods
+- SVG is now the default and only rendering method
+- Simplified codebase with reduced file size
+- Modern web interface included
+- Automatic sizing based on QR code complexity
+
+## Credits
+
+Based on [QRCode.js by davidshimjs](https://github.com/davidshimjs/qrcodejs)
