 Chef
 ----
+`Chef <https://www.chef.io/chef/>`_  is a systems and cloud infrastructure automation 
+framework that makes it easy to deploy servers and applications to any physical,

+as configuration elements which implement your polices.

+Chef clients run on every server that is part of your infrastructure and these regularly 
+check with your Chef server to ensure your system is always aligned and represents the 
+desired state. Since each individual server has its own distinct Chef client, each server 
+configures itself and this distributed approach makes Chef a scalable automation platform.
