-==========================
+This project is no longer maintained.
 
-**DEPRECATION NOTICE:** The openstack-ansible-security role is deprecated and
-will be retired soon. Consumers of this role should use the
-[ansible-hardening](https://github.com/openstack/ansible-hardening) role
-instead.

+source code management system.  To see the contents of this

-Overview
---------
+This project has been replaced by
+[ansible-hardening](https://docs.openstack.org/ansible-hardening/latest/).
 
-The openstack-ansible security role applies security hardening configurations
-from the [Security Technical Implementation Guide(STIG)](http://iase.disa.mil/stigs/Pages/index.aspx)
-to systems running Ubuntu 14.04, Ubuntu 16.04, CentOS 7, and Red Hat
-Enterprise Linux 7.
-
-The role is part of the
-[OpenStack-Ansible project](https://git.openstack.org/cgit/openstack/openstack-ansible),
-which deploys enterprise-grade OpenStack clouds using Ansible.  However, the
-role can easily be used outside of an OpenStack environment to secure hosts,
-virtual machines, and containers.
