+Devstack (Deprecated) instructions
+==================================
+
+`Devstack <https://github.com/openedx-unsupported/devstack>`_ is no longer a supported development environment.
 
-`Devstack <https://edx.readthedocs.io/projects/edx-installing-configuring-and-running/en/latest/installation/index.html>`_.
 If you start Devstack with ``make dev.up`` that should give you everything you need as a companion to this frontend.
