+# OCR Plugin
+
+This is a README file for the OCR plugin. This plugin uses the `RapidOCR` library to perform OCR (Optical Character Recognition) on image files and updates the metadata of the entity with the OCR results.
+
+## How to Run
+
+To run this OCR plugin, follow the steps below:
+
+1. **Install the required dependencies:**
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+2. **Run the FastAPI application:**
+
+   You can run the FastAPI application using `uvicorn`. Make sure you are in the directory where `main.py` is located.
+
+   ```bash
+   uvicorn main:app --host 0.0.0.0 --port 8000
+   ```
+
+3. **Integration with memos:**
+
+   ```sh
+   $ python -m memos.commands plugin create ocr http://localhost:8000
+   Plugin created successfully
+   ```
+
+   ```sh
+   $ python -m memos.commands plugin ls
+
+   ID  Name    Description    Webhook URL
+    1  ocr                    http://localhost:8000/
+   ```
+
+   ```sh
+   $ python -m memos.commands plugin bind --lib 1 --plugin 1
+   Plugin bound to library successfully
+   ```
+
+## Endpoints
+
+- `GET /`: Health check endpoint. Returns `{"healthy": True}` if the service is running.
+- `POST /`: OCR endpoint. Accepts an `Entity` object and a `Location` header. Performs OCR on the image file and updates the entity's metadata with the OCR results.
+
+## Metadata
+
+The OCR results are stored in the metadata field named `ocr_result` with the following structure:
