## Overview

Smart Parking System is a React client for signing in, viewing parking availability, reserving or cancelling a spot, and presenting payment choices. Its sampled runtime is concentrated in `frontend/src/App.js`: that component handles Firebase authentication and Firestore slot updates, and invokes an email confirmation service for reservations. Payment methods are shown in the UI, but no payment processor is evidenced. The README is empty, and the separate `src/` and backend modules are unsampled or empty, so their relationships and capabilities are not inferred.

Main entry points: [`frontend/src/App.js`](https://github.com/srikanta2006/smart-parking/blob/main/frontend/src/App.js) (Parking app), [`frontend/src/index.js`](https://github.com/srikanta2006/smart-parking/blob/main/frontend/src/index.js) (React entry), [`frontend/src/emailService.js`](https://github.com/srikanta2006/smart-parking/blob/main/frontend/src/emailService.js) (Email sender), [`frontend/src/firebaseConfig.js`](https://github.com/srikanta2006/smart-parking/blob/main/frontend/src/firebaseConfig.js) (Firebase configuration)
