+# QRCode Support in OpenCV.js
+
+This document explains the current state of QR code functionality in opencv-js.
+
+## Available QR Code Functionality
+
+### QRCodeDetector ✅
+The `QRCodeDetector` class is fully available and functional:
+
+```typescript
+const detector = new cv.QRCodeDetector();
+const image = cv.imread(imageElement);
+const points = new cv.Mat();
+const straightQrcode = new cv.Mat();
+
+// Detect and decode QR code
+const decodedText = detector.detectAndDecode(image, points, straightQrcode);
+console.log("Decoded text:", decodedText);
+```
+
+### QRCodeDetectorAruco ✅
+Enhanced QR code detection using ArUco-based methods:
+
+```typescript
+const params = new cv.QRCodeDetectorAruco_Params();
+const detector = new cv.QRCodeDetectorAruco(params);
+```
+
+### QRCodeEncoder Constants ✅
+All QRCodeEncoder constants are available:
+
+```typescript
+// Correction levels
+cv.QRCodeEncoder_CORRECT_LEVEL_L  // Low
+cv.QRCodeEncoder_CORRECT_LEVEL_M  // Medium  
+cv.QRCodeEncoder_CORRECT_LEVEL_Q  // Quartile
+cv.QRCodeEncoder_CORRECT_LEVEL_H  // High
+
+// Encoding modes
+cv.QRCodeEncoder_MODE_NUMERIC
+cv.QRCodeEncoder_MODE_ALPHANUMERIC
+cv.QRCodeEncoder_MODE_BYTE
+cv.QRCodeEncoder_MODE_KANJI
+cv.QRCodeEncoder_MODE_ECI
+cv.QRCodeEncoder_MODE_STRUCTURED_APPEND
+cv.QRCodeEncoder_MODE_AUTO
+
+// ECI encodings
+cv.QRCodeEncoder_ECI_UTF8
+```
+
+### QRCodeEncoder Enums ✅
+Enum classes are available:
+
+```typescript
+cv.QRCodeEncoder_CorrectionLevel
+cv.QRCodeEncoder_EncodeMode  
+cv.QRCodeEncoder_ECIEncodings
+```
+
+## Missing Functionality
+
+### QRCodeEncoder Class ❌
+The actual `QRCodeEncoder` class is **not available** in the current OpenCV.js build, although TypeScript definitions are provided for future compatibility.
+
+```typescript
+// This will throw an error:
+const encoder = new cv.QRCodeEncoder(); // ❌ Not available
+```
+
+## Workarounds
+
+For QR code generation, consider using external libraries such as:
+
+- [qrcode](https://www.npmjs.com/package/qrcode)
+- [qr-code-generator](https://www.npmjs.com/package/qr-code-generator)
+- [qrious](https://www.npmjs.com/package/qrious)
+
+## Future Support
+
+The TypeScript definitions for `QRCodeEncoder` are included for when this functionality becomes available in future OpenCV.js builds.
