## 🚀 Installation Guide

### Prerequisites

- **Web Server**: Apache (XAMPP, WAMP, LAMP, or similar)
- **PHP**: Version 7.4 or higher

### Step 1: Setup Database

1. Open **phpMyAdmin** or MySQL command line
2. Import the database schema:
   ```bash
   mysql -u root -p < database_schema.sql
   ```
   Or manually run the SQL file in phpMyAdmin

3. The schema will create:
   - Database: `iscan_db`
   - Tables: `certificate_of_live_birth`, `users`, `activity_logs`
   - Views: `vw_active_certificates`, `vw_certificate_statistics`
   - Default admin user (username: `admin`, password: `admin123`)

### Step 2: Configure Database Connection

1. Open `includes/config.php`
2. Update database credentials if needed:
   ```php
   define('DB_HOST', 'localhost');

   define('DB_USER', 'root');
   define('DB_PASS', '');
   ```

### Step 3: Set File Permissions

Ensure the `uploads/` folder has write permissions:

**On Linux/Mac:**
```bash
chmod 755 uploads/
```

**On Windows (XAMPP):**
- Right-click `uploads` folder → Properties → Security
- Give "Full Control" to the web server user

### Step 4: Access the Application
