 Salted-Rails: Provision rails using salt to vagrant or capistrano controlled systems
 
-EXPERIMENTAL
+This gem inspects .ruby-version, config/database.yml, Gemfile and Gemfile.lock to generate salt pillar files to control the configuration of the system. 
 
+THIS GEM IS IN THE EXPERIMENTAL STAGE (pre pre alpha)! EXPECT THINGS TO CHANGE AND BREAK WITHOUT NOTICE!
+
 This configures vagrant in the way that I personally like:
 * ubunutu 12.04 (LTS) 32bit from cloud-images.ubuntu.com (up to date packages and more memory free for systems < 4GB memory)
 * forward ssh agent
 * digital ocean default to 'San Francisco 1'
 * salt provisioning based on rails Gemfile[.lock], database.yml and .ruby-version configuration

+The ubuntu_mirror value can also be:
+* 'mirror' - Configures mirror: option to auto select from http://mirrors.ubuntu.com/mirrors.txt
+* 'internode' - an australian ISP (mine ;)
+* a country code - eg 'au', 'uk', 'us' etc
+* url of mirror - specify the full url (in the same format as mirrors.txt above)
