+
+## Configuration Options
+
+| Option | Description | Default | Required |
+|--------|-------------|---------|----------|
+| `api_key` | Your Firecrawl API key | - | Yes |
+| `api_url` | Firecrawl API endpoint | `https://api.firecrawl.dev` | No |
+| `max_retries` | Maximum retry attempts | 3 | No |
+| `timeout` | Request timeout (seconds) | 30 | No |

+
+## Verification
+
+### 1. Check Plugin Installation
+
+```bash
+# Check if the plugin directory exists
+ls -la /opt/ragflow/plugin/firecrawl/
+
+# Should show:
+# __init__.py
+# firecrawl_connector.py
+# firecrawl_config.py
+# firecrawl_processor.py
+# firecrawl_ui.py
+# ragflow_integration.py
+# requirements.txt
+```
+
+### 2. Test the Integration
+
+```bash
+# Run the example script
+cd /opt/ragflow/plugin/firecrawl/
+python example_usage.py
+```
+
+### 3. Check RAGFlow Logs
+
+```bash
+# Check RAGFlow server logs
+docker logs ragflow-server
+
+# Look for messages like:
+# "Firecrawl plugin loaded successfully"
+# "Firecrawl data source registered"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Plugin not appearing in RAGFlow**:
+   - Check if the plugin directory is in the correct location
+   - Restart RAGFlow services
+   - Check RAGFlow logs for errors

+   - Check for typos in the configuration
+
+3. **Connection Timeout**:
+   - Increase the timeout value in configuration
+   - Check your network connection
+   - Verify the API URL is correct
+
+4. **Rate Limiting**:
+   - Increase the `rate_limit_delay` value
+   - Reduce the number of concurrent requests
+   - Check your Firecrawl usage limits
+
+### Debug Mode
+
+Enable debug logging to see detailed information:
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+### Check Dependencies
+
+```bash
+# Verify all dependencies are installed
+pip list | grep -E "(aiohttp|pydantic|requests)"
+
+# Should show:
+# aiohttp>=3.8.0
+# pydantic>=2.0.0
+# requests>=2.28.0
+```
+
+## Uninstallation
