-# Python 'hello' template
+# Python HTTP Function
 
-Welcome to your new Python function project! The boilerplate function
-code can be found in [`func.py`](./func.py). This function will
-simply print 'Hello, World!' if a request is received successfuly.
+## Introduction
 
-## Endpoints
+A Python HTTP function built with ASGI protocol support. The implementation 
+provides a simple HTTP endpoint that responds with "Hello World!" to incoming 
+requests.
 
-Running this function will expose three endpoints.
+The function is structured as a class-based implementation with proper lifecycle
+management, including configurable startup and shutdown hooks.
 
-  * `/` The endpoint for your function.
-  * `/health/readiness` The endpoint for a readiness health check
-  * `/health/liveness` The endpoint for a liveness health check
+## Recommended Deployment
 
-The health checks can be accessed in your browser at
-[http://localhost:8080/health/readiness]() and
-[http://localhost:8080/health/liveness]().
+> [!NOTE]
+> We recommend using the host builder.
+> This feature is currently behind a flag because its not available for all the
+> languages yet so you will need to enable it.
 
-You can use `func invoke` to send an HTTP request to the function endpoint.
+```bash
+# Enable the host builder
+export FUNC_ENABLE_HOST_BUILDER=1
+
+# Deploy your code to cluster
+# Make sure to set the builder to use it
+func deploy --builder=host
+
+# Local development and testing
+func run --builder=host --container=false
+```
+
+## Customization
+
+- This function uses the ASGI (Asynchronous Server Gateway Interface) 3.0
+specification therefore its compatible with the signature `handle(scope, receive, send)`
+
+### Lifecycle Management
+The function provides lifecycle hooks:
+- **start()**: Initialization hook called when function instances are created
+- **stop()**: Cleanup hook, ensuring graceful termination and resource cleanup
+- **alive()**: Health check exposed at `/health/liveness`
+- **ready()**: Readiness check exposed at `/health/readiness`
 
 ## Testing
 
-This function project includes a [unit test](./test_func.py). Update this
-as you add business logic to your function in order to test its behavior.
+The function includes unit tests that verify the HTTP handler behavior. 
+Tests are located in the `tests/` directory and use pytest with asyncio support.
+
+To run the tests:
 
-```console
-python test_func.py
+```bash
+# Install dependencies (if not already installed)
+pip install -e .
+
+# Run tests
+pytest
+
+# Run tests with verbose output
+pytest -v
 ```
+
+### Test Structure
+
+Tests are organized in the `tests/` directory with the current test file 
+`test_func.py` verifying that the ASGI handler returns a proper 200 OK response.
+The testing framework uses pytest with asyncio support, configured in `pyproject.toml`.
+
+### Writing New Tests
+
+To add new tests, create files named `test_*.py` in the `tests/` directory. 
+For async functions, use the `@pytest.mark.asyncio` decorator. Mock ASGI 
+components by creating mock `scope`, `receive`, and `send` functions as shown 
+in the existing test. You can also test lifecycle methods like `start()`, 
+`stop()`, `alive()`, and `ready()` by calling them directly on a function instance.
