+# OCR Text Recognition
+
+This skill uses PaddleOCR for text recognition, supporting both Chinese and English.
+
+## Quick Start
+
+### Basic Usage
+
+Perform OCR recognition directly on image or PDF files:
+
+```python
+from paddleocr import PaddleOCR
+
+ocr = PaddleOCR(lang='ch')
+result = ocr.predict("file_path.jpg")
+```
+
+## Dependency Installation
+
+Install dependencies before first use:
+
+```bash
+pip3 install paddlepaddle paddleocr
+```
+
+## Output Format
+
+Recognition results return JSON containing:
+- `rec_texts`: List of recognized text
+- `rec_scores`: Confidence score for each text
+
+## Typical Use Cases
+
+1. **PDF Scans**: Use PyMuPDF to extract images first, then OCR
+2. **Image Text Recognition**: Perform OCR directly on images
+3. **Multi-page PDFs**: Process page by page
+
+## Scripts
+
+Common scripts are located in the `scripts/` directory.
