+# xCloud Native WordPress Deployment
+
+WordPress on xCloud is fully managed — no Docker needed.
+
+## Method 1: One-Click Install (Recommended for new sites)
+
+1. Server → New Site → WordPress tab
+2. Fill in: site title, admin email, admin username, admin password
+3. PHP version: 8.1 or 8.2 recommended
+4. Web stack: NGINX (recommended) or OpenLiteSpeed
+5. Click Deploy — WordPress installed automatically
+
+## Method 2: Git Deploy (existing WordPress sites)
+
+Repository setup:
+```
+your-repo/
+├── wp-content/
+│   ├── plugins/
+│   ├── themes/
+│   └── uploads/     ← add to .gitignore
+├── wp-config.php    ← use env vars for DB credentials
+└── ...
+```
+
+wp-config.php — use environment variables:
+```php
+define('DB_NAME',     getenv('DB_NAME'));
+define('DB_USER',     getenv('DB_USER'));
+define('DB_PASSWORD', getenv('DB_PASSWORD'));
+define('DB_HOST',     getenv('DB_HOST') ?: 'localhost');
+```
+
+xCloud UI Steps:
+1. Server → New Site → WordPress tab → Git option
+2. Connect repo
+3. Add DB environment variables
+4. Deploy
+
+## Performance Recommendations
+
+- Enable NGINX FastCGI Cache in xCloud site settings
+- Enable Redis Object Cache (available as xCloud addon)
+- Set PHP version to 8.2+
+- Enable AI Bot Blocker in security settings
