 # Cookbooks #
 
 The cookbooks have been designed and written in such a way that they can be used to deploy individual service components on _any_ of the nodes in the infrastructure; in short they can be used for single node 'all-in-one' installs (for testing), right up to multi/many node production installs. In order to achieve this flexibility, they are configured by attributes which may be used to override search. Chef 11 or later is currently required. Ruby 1.9.x is considered the minimum supported version of Ruby as well. Most users of this repository test with the full-stack Chef 11 client and a Chef server (Chef Solo is not explicity supported).
