## 🛠️ Installation Instructions

### Prerequisites

- **Web Hosting**: Shared hosting account (Hostinger, cPanel, etc.)
- **PHP**: Version 7.4 or higher
- **MySQL**: Version 5.7 or higher
- **Apache**: With mod_rewrite enabled

### Step 1: Download and Extract

1. Download all the files provided in the artifacts
2. Create a new folder named `relevant-reflex` on your computer
3. Copy all files into this folder maintaining the directory structure

### Step 2: Database Setup

1. **Login to phpMyAdmin** via your hosting control panel
2. **Create a new database**:
   - Database name: `relevant_reflex_db` (or your preferred name)
   - Collation: `utf8mb4_unicode_ci`
3. **Import the schema**:
   - Click on your database
   - Go to "Import" tab
   - Choose the `database_schema.sql` file
   - Click "Go" to execute

### Step 3: Configuration

1. **Edit config.php**:
   ```php
   define('DB_HOST', 'localhost');
   define('DB_USER', 'your_db_username');    // From your hosting panel
   define('DB_PASS', 'your_db_password');    // From your hosting panel
   define('DB_NAME', 'relevant_reflex_db');  // Your database name
   define('SITE_URL', 'https://yourdomain.com'); // Your actual domain
   ```

2. **Update site settings** in other files if needed

### Step 4: File Upload

1. **Connect via FTP/File Manager**:
   - Use your hosting panel's file manager or FTP client
   - Navigate to `public_html` directory (or your domain's root)

2. **Upload files**:
   - Upload all files maintaining the folder structure
   - Ensure permissions are set correctly:
     - Files: 644
     - Directories: 755
     - config.php: 600 (more secure)

### Step 5: Testing

1. **Visit your website**: `https://yourdomain.com`
2. **Default admin login**:
   - Username: `admin`
   - Email: `admin@relevantreflex.com`
   - Password: `admin123`
   - **⚠️ Change this immediately after first login!**

3. **Test all features**:
   - Dashboard loading
   - User management
   - Panel creation
   - Mobile responsiveness

### Step 6: Security Hardening

1. **Change default admin password**
2. **Update config.php** with strong database credentials
3. **Enable SSL certificate** (usually free with hosting)
4. **Uncomment HTTPS redirect** in .htaccess:
   ```apache
   RewriteCond %{HTTPS} off
   RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
   ```

## 🎨 Customization

### Changing Colors and Theme

All colors are centralized in `assets/css/main.css` at the top:

```css
:root {
    --primary-color: #0066cc;        /* Change main brand color */
    --primary-hover: #0052a3;        /* Hover state */
    --success-color: #28a745;        /* Success messages */
    --warning-color: #ffc107;        /* Warnings */
    --danger-color: #dc3545;         /* Errors */
    /* ... more color variables */
}
```

Simply update these values to match your brand colors.

### Adding Your Logo

1. **Replace the RR logo**:
   - Update the `.logo` content in `includes/navigation.php`
   - Or replace with an image: `<img src="assets/images/logo.png" alt="Your Logo">`

2. **Update favicon**:
   - Add your `favicon.ico` to the root directory
   - Update the reference in `includes/header.php`

### Custom Styling

- **Main styles**: `assets/css/main.css`

- **Dashboard styles**: `assets/css/dashboard.css`
