+## 🔄 Queue System
+
+The framework includes a powerful queue system for background job processing with support for multiple drivers.
+
+### Features
+- **Background Job Processing** - Asynchronous task execution
+- **Multiple Drivers** - Database and Redis support
+- **Email Queues** - Reliable email delivery
+- **File Processing** - Image resize, file conversion, compression
+- **Job Retry Logic** - Automatic retry with exponential backoff
+- **Failed Job Handling** - Dead letter queue for failed jobs
+- **CLI Workers** - Command-line queue processors
+
+### Configuration
+
+Add to your `.env` file:
+```bash
+# Queue driver (database or redis)
+QUEUE_DRIVER=database
+
+# Redis configuration (if using Redis driver)
+REDIS_HOST=127.0.0.1
+REDIS_PORT=6379
+```
+
+### Usage
+
+#### Dispatching Jobs
+```php
+// Email jobs
+queue_email('user@example.com', 'Welcome!', 'Welcome message');
+
+// File processing jobs
+queue_file_processing('/path/to/image.jpg', 'resize', ['width' => 800, 'height' => 600]);
+
+// Custom jobs
+use App\Queue\Jobs\SendEmailJob;
+$job = new SendEmailJob('user@example.com', 'Subject', 'Message');
+dispatch($job, 'emails');
+```
+
+#### Processing Jobs
+```bash
+# Start queue worker
+php console queue work default
+
+# Process specific queue
+php console queue work emails
+
+# Process limited number of jobs
+php console queue work files 10
+
+# Check queue status
+php console queue status emails
+```
+
+### Built-in Job Types
+
+**SendEmailJob** - Email delivery
+- Automatic retry on failure
+- SMTP configuration support
+- HTML/text email support
+
+**ProcessFileJob** - File processing
+- Image resizing
+- File compression
+- Format conversion
+- Batch processing support
+
+### Creating Custom Jobs
+
+```php
+use App\Queue\Jobs\BaseJob;
+
+class CustomJob extends BaseJob
+{
+    private $data;
+    
+    public function __construct($data)
+    {
+        $this->data = $data;
+        $this->maxRetries = 3;
+        $this->delay = 30; // seconds
+    }
+    
+    public function handle(): bool
+    {
+        // Your job logic here
+        return true;
+    }
+    
+    public function failed(\Exception $exception): void
+    {
+        // Handle job failure
+    }
+}
+```
+
+### Queue Drivers
+
+**Database Driver**
+- Uses MySQL/PostgreSQL for job storage
+- Automatic table creation
+- Transaction support
+- No external dependencies
+
+**Redis Driver**
+- High performance
+- Atomic operations
+- Delayed job support
+- Requires Redis extension
+
 ## 💻 CLI Support
 
 The framework includes a powerful command-line interface for development tasks.
