-Compatibility
-=============
-
-**IMPORTANT**: If you have an earlier version of the azure package
-(version < 1.0), you should uninstall it before installing this package.
-
-You can check the version using pip:
-
-.. code:: shell
-
-    pip freeze
-
-If you see azure==0.11.0 (or any version below 1.0), uninstall it first:
-
-.. code:: shell
-
-    pip uninstall azure
