+Microsoft Azure SDK for Python
+==============================
+
+This is the Microsoft Azure MyService Management Client Library.
+
+Azure Resource Manager (ARM) is the next generation of management APIs that
+replace the old Azure Service Management (ASM).
+
+This package has been tested with Python 2.7, 3.4, 3.5, 3.6 and 3.7.
+
+For the older Azure Service Management (ASM) libraries, see
+`azure-servicemanagement-legacy <https://pypi.python.org/pypi/azure-servicemanagement-legacy>`__ library.
+
+For a more complete set of Azure libraries, see the `azure <https://pypi.python.org/pypi/azure>`__ bundle package.
+
+
+Usage
+=====
+
+For code examples, see `MyService Management
+<https://docs.microsoft.com/python/api/overview/azure/>`__
+on docs.microsoft.com.
+
+
+Provide Feedback
+================
+
+If you encounter any bugs or have suggestions, please file an issue in the
+`Issues <https://github.com/Azure/azure-sdk-for-python/issues>`__
+section of the project.
