## ⚡ Quick Start

Perform OCR on a PDF using the **default RapidOCR** engine, export to **Markdown**:

```bash
docling-ocr   --engine rapidocr   --input ./scanned_document.pdf   --format md   --output ./scanned_document.md
```

_No extra flags needed!_

## 🛠️ CLI Reference

```plain
Usage: docling-ocr [OPTIONS]

Options:
  -e, --engine [easyocr|tesseract_py|tesseract_cli|rapidocr]
                                  OCR engine (default: rapidocr)
  -i, --input PATH                 Input file path (.pdf, image)
  -f, --format [md|json|html]      Output format (default: md)
  -o, --output PATH                Output file path
  -h, --help                       Show this message and exit

## 🎯 Examples

### 1. EasyOCR on an Image

```bash
docling-ocr   --engine easyocr   --input invoice.jpg   --format json   --output invoice.json
```

### 2. Tesseract CLI on PDF → hOCR

```bash
docling-ocr   --engine tesseract_cli   --input contract.pdf   --format html   --output contract.hocr.html
```

### 3. Batch Processing (RapidOCR default)

```bash
for pdf in reports/*.pdf; do
  out="${pdf%.pdf}.md"
  docling-ocr     --input "$pdf"     --output "$out"
done
```
