 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.
 
+Chef works by using custom recipes (configuration elements), implemented in cookbooks. Cookbooks, which are basically 
+packages for infrastructure choices, are usually stored in your Chef server.
