+# Extension package for Azure Storage Python libraries
+This package contains a set of C-Extension modules intended to be used with the other Azure Storage Python SDK libraries.
+
+## Getting started
+
+### Prerequisites
+* Python 3.8 or later is required to use this package. For more details, please read our page on [Azure SDK for Python version support policy](https://github.com/Azure/azure-sdk-for-python/wiki/Azure-SDKs-Python-version-support-policy).
+
+### Install the package
+This package is not meant to be used standalone and is meant to accompany other Azure Storage Python SDK libraries. However it can be installed and used standalone as well.
+
+Install the Azure Storage Extensions library for Python with [pip](https://pypi.org/project/pip/):
+
+```bash
+pip install azure-storage-extensions
+```
+
+Please note that this package contains [C-Extension modules](https://docs.python.org/3/extending/extending.html) and therefore you must install the correct wheel for your
+particular platform. We distribute many pre-built wheels for a wide variety of platforms on PyPi and `pip` will attempt to install the wheel meant for your platform. If
+however, a wheel is not available for your platform, we also distribute the source code on PyPi so `pip` will attempt to build the module at install time, assuming you have
+a compiler available. If you encounter any issues installing this package, please feel to open an Issue.
+
+## Extensions
+This section contains the list of available extensions and how to use them.
+
+### Storage CRC64
+The `crc64` extension provides an implementation of the CRC64 algorithm, including the custom polynomial, that is used by the Azure Storage service. It can be used to compute
+the crc64 hash of `bytes` data, including given an initial hash.
+
+```py
+from azure.storage.extensions import crc64
+
+data = b'Hello World!'
+result = crc64.compute_crc64(data, 0)
+
+# Chain together calculations
+data2 = b'Goodbye World!`
+result2 = crc64.compute_crc64(data2, result)
+```
