+
+
+## Getting started
+
+### Prerequisites
+* Python 3.8 or later is required to use this package. For more details, please read our page on [Python Functions version support policy](https://learn.microsoft.com/en-us/azure/azure-functions/functions-versions?tabs=isolated-process%2Cv4&pivots=programming-language-python#languages).
+
+
+### Instructions
+1. Follow the guide to [create an app](https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-python?tabs=windows%2Cbash%2Cazure-cli%2Cbrowser).
+2. Ensure your app is using programming model v2 and contains a http trigger function.
+3. Add azure-functions-extension-fastapi to your requirement.txt
+4. Import Request and different types of responses from azure.functions.extensions.fastapi in your httptrigger functions.
+5. Change the request and response types to ones imported from azure.functions.extensions.fastapi.
+6. Run your function app and try it out!
+
+### Bind to the FastApi-type
+The Azure Functions Extension FastApi library for Python allows you to create a function app with FastApi Request or Response types. When your function runs, you will receive the request of FastApi Request type and you can return a FastApi response type instance. FastApi is one of top popular python web framework which provides elegant and powerful request/response types and functionalities to users. With this integration, you are empowered to use request/response the same way as using them in native FastApi. A good example is you can do http streaming upload and streaming download now! Feel free to check out [Fastapi doc] for further reference (https://fastapi.tiangolo.com/reference/responses/?h=custom)
+
+
+```python
+# This Azure Function receives streaming data from a client and processes it in real-time.
+# It demonstrates streaming upload capabilities for scenarios such as uploading large files,
+# processing continuous data streams, or handling IoT device data.
+
+import azure.functions as func
+from azure.functions.extension.fastapi import Request, JSONResponse
+
+app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
+
+@app.route(route="streaming_upload", methods=[func.HttpMethod.POST])
+async def streaming_upload(req: Request) -> JSONResponse:
+    """Handle streaming upload requests."""
+    # Process each chunk of data as it arrives
+    async for chunk in req.stream():
+        process_data_chunk(chunk)
+
+    # Once all data is received, return a JSON response indicating successful processing
+    return JSONResponse({"status": "Data uploaded and processed successfully"})
+
+def process_data_chunk(chunk: bytes):
+    """Process each data chunk."""
+    # Add custom processing logic here
+    pass
+```
+
+## Next steps
+
+### More sample code
+
+Get started with our [FastApi samples](hhttps://github.com/Azure/azure-functions-python-extensions/tree/main/azure-functions-extension-fastapi/samples).
+
+Several samples are available in this GitHub repository. These samples provide example code for additional scenarios commonly encountered while working with FastApi:
+
+* [fastapi_samples_streaming_upload](https://github.com/Azure/azure-functions-python-extensions/tree/main/azure-functions-extension-fastapi/samples/fastapi_samples_streaming_upload) - An example on how to send and receiving a streaming request within your function.
+
+* [fastapi_samples_streaming_download](https://github.com/Azure/azure-functions-python-extensions/tree/main/azure-functions-extension-fastapi/samples/fastapi_samples_streaming_download) - An example on how  to send your http response via streaming to the caller.t
