+FunctionStream SDK is a powerful Python library for building and deploying serverless functions that process messages
+from Apache Pulsar. It provides a simple yet flexible framework for creating event-driven applications with robust error
+handling, metrics collection, and resource management.
 
 ## Features
 
 - **Easy Function Development**: Simple API for creating serverless functions
 - **Message Processing**: Built-in support for Apache Pulsar message processing
 - **Metrics Collection**: Automatic collection of performance metrics
 - **Resource Management**: Efficient handling of connections and resources
-- **Graceful Shutdown**: Proper cleanup of resources during shutdown
 - **Configuration Management**: Flexible configuration through YAML files
-- **Schema Validation**: Input and output schema validation
 - **Error Handling**: Comprehensive error handling and logging
 
 ## Installation
 
 ```bash
-pip install fs-sdk
+pip install function-stream
 ```
 
 ## Quick Start
 
 1. Create a function that processes messages:
 
 ```python
-from fs_sdk import FSFunction
+from function_stream import FSFunction
 
 async def my_process_function(request_data: dict) -> dict:
     # Process the request data

 ## Best Practices
 
 1. **Error Handling**
-   - Always handle exceptions in your process functions
-   - Use proper logging for debugging
-   - Implement graceful shutdown
