+# Backend Setup for Contact Form
+
+This document explains how to set up the backend for the contact form to send emails to bayan10kh@gmail.com.
+
+## Prerequisites
+
+1. PHP 7.0 or higher
+2. Composer (PHP dependency manager)
+
+## Installation Steps
+
+1. Install PHPMailer via Composer:
+   ```bash
+   composer install
+   ```
+
+2. Configure Gmail SMTP:
+   - Enable 2-factor authentication on your Gmail account
+   - Generate an App Password for the Gmail account
+   - Update the `contact_handler.php` file with your credentials:
+     ```php
+     $mail->Username   = 'scandrone308@gmail.com'; // Your Gmail address
+     $mail->Password   = 'your_app_password';      // Your Gmail App Password
+     ```
+
+3. Deploy the files to a PHP-enabled web server
+
+## How It Works
+
+1. The React frontend sends form data to `contact_handler.php` via AJAX
+2. The PHP script validates the data and sends an email using PHPMailer
+3. The email is sent via Gmail SMTP to bayan10kh@gmail.com
+
+## Security Notes
+
+- Never commit your actual Gmail credentials to version control
+- Use environment variables or a separate config file for sensitive data
+- Ensure your App Password is kept secure
+
+## Troubleshooting
+
+If emails aren't being sent:
+1. Check that Composer dependencies were installed correctly
+2. Verify your Gmail credentials and App Password
+3. Ensure your hosting provider allows SMTP connections
+4. Check the server error logs for more details
