-*******************

 Description
 ***********
 
-This repository is a collection of tools and scripts that edx.org uses to deploy
-openedx. The purpose of this repository is to share portions of our toolchain
-with the community. This repository is *not* the best way to get started running
-openedx. For that, please look at `Open EdX Installation options`_, which contains
-links to the recommended paths for new installations.
-
-**Important**: The Open edX configuration scripts need to be run as root on
-your servers and will make changes to service configurations including, but not
-limited to, sshd, dhclient, sudo, apparmor and syslogd. Our scripts are made
-available as we use them and they implement our best practices. We strongly
-recommend that you review everything that these scripts will do before running
-them against your servers. We also recommend against running them against
-servers that are hosting other applications. No warranty is expressed or
-implied.
-
-For more information including installation instructions please see the `OpenEdX
-Wiki`_.
+A collection of configuration scripts using Ansible for deploying edx.org.
