            <div class="instructions">
                <h3>Step 1: Download & Save</h3>
                <ul>
                    <li>Save the file above as <span class="highlight">nukeit.php</span></li>
                    <li>Upload to your <strong>development server</strong> (never production)</li>
                    <li>Place it in your project root or a protected directory</li>
                </ul>

                <h3>Step 2: Configure Password</h3>
                <p>Open <span class="highlight">nukeit.php</span> and change line 17:</p>
                <pre>define('NUKEIT_PASSWORD', 'YOUR_SECRET_PASSWORD');</pre>
                
                <p><strong>For production security</strong>, generate a proper hash:</p>
                <pre>// Run this in PHP:
echo password_hash('your-secret-password', PASSWORD_DEFAULT);
// Output: $2y$10$...

// Then change line 17 to:
define('NUKEIT_PASSWORD', '$2y$10$...your-hash...');

// AND modify the authenticate() function to:
return password_verify($password, NUKEIT_PASSWORD);</pre>

                <h3>Step 3: Configure Targets</h3>
                <p>Edit the <span class="highlight">$nukeDirectories</span> array to match your folders:</p>

define('DB_NAME', 'your_dev_db');
