 # Kew Task Queue Manager
 
-A flexible and robust asynchronous task queue manager for Python applications with support for multiple priority queues.
+A robust, Redis-backed asynchronous task queue manager for Python applications with support for priority-based queues and circuit breaker patterns.
 
 ## Features
 
 - Multiple named queues with independent configurations
-- Priority-based task processing
-- Asynchronous task execution
+- Priority-based task scheduling with millisecond precision
+- Redis-backed persistence for reliability
 - Configurable worker pools per queue
-- Task status tracking and monitoring
-- Automatic cleanup of completed tasks
+- Built-in circuit breaker for fault tolerance
+- Comprehensive task lifecycle management
+- Automatic task expiration (24-hour default)
+- Detailed logging and monitoring
+- Graceful shutdown handling
 - Thread-safe operations
-- Comprehensive logging

+
+## Advanced Features
+
+### Circuit Breaker
+
+Each queue has a built-in circuit breaker that helps prevent cascade failures:
+
+- Opens after 3 consecutive failures (configurable)
+- Auto-resets after 60 seconds (configurable)
+- Provides circuit state monitoring
 
-# Wait for all tasks in a queue
-await manager.wait_for_queue("critical", timeout=60)
+### Task Expiration
+
+Tasks automatically expire after 24 hours (configurable) to prevent resource leaks.
+
+### Redis Configuration
+
+```python
+manager = TaskQueueManager(
+    redis_url="redis://username:password@hostname:6379/0",
+    cleanup_on_start=True  # Optional: cleans up existing tasks on startup
+)
 ```
 
+## Error Handling
+
+The system handles various error scenarios:
+
+- `TaskAlreadyExistsError`: Raised when submitting a task with a duplicate ID
+- `TaskNotFoundError`: Raised when querying a non-existent task
+- `QueueNotFoundError`: Raised when accessing an undefined queue
+- `QueueProcessorError`: Raised for queue processing failures
+
