-The CORS extension provides support for `Cross-Origin Resource Sharing
-(CORS) <https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS>`_. CORS is a
-mechanism that allows web applications running on different origins to access
-resources from each other. For example, a web application running on
-``https://example.com`` can access resources from ``https://api.example.com``.
-
-To enable CORS support, create an instance of the

-Example::
-
-    from microdot import Microdot
-    from microdot_cors import CORS
