+## Error Tracking with Sentry
+
+AnonChat includes integration with Sentry for error tracking and performance monitoring. This helps identify and diagnose issues in production environments.
+
+### Features
+
+- Automatic error capturing and reporting
+- Performance monitoring
+- Contextual information for better debugging
+- Real-time alerts for critical issues
+
+### Configuration
+
+To enable Sentry integration:
+
+1. Sign up for a free Sentry account at [sentry.io](https://sentry.io)
+2. Create a new project and get your DSN (Data Source Name)
+3. Set the `SENTRY_DSN` environment variable in your `.env` file or deployment environment:
+
+```
+SENTRY_DSN=https://your-sentry-project-key@sentry.io/your-project-id
+```
+
+When the `SENTRY_DSN` variable is set, error tracking will be automatically enabled when the application starts.
+
