+# Paddle OCR loader
+
+```bash
+pip install llama-index-readers-paddle-ocr
+```
+
+This loader reads the equations, symbols, and tables included in the PDF.
+
+Users can input the path of the academic PDF document `file` which they want to parse. This OCR understands LaTeX math and tables.
+
+## Usage
+
+Here's an example usage of the PDFPaddleOCR.
+
+```python
+from llama_index.readers.paddle_ocr import PDFPaddleOCR
+
+reader = PDFPaddleOCR()
+
+pdf_path = Path("/path/to/pdf")
+
+documents = reader.load_data(pdf_path)
+```
+
+## Miscellaneous
+
+An `output` folder will be created with the same name as the pdf and `.mmd` extension.
