Please install the following before the event

RVM - Ruby Version Management. This will allow you to install multiple version of Ruby and thus work we do will not interfere with other things you might be doing. https://rvm.io/

Ruby 2.1.5 (or any 2.1.x if you prefer it) rvm install ruby-2.1.5

Sublime Text editor (http://www.sublimetext.com/download)

AWS ruby gem version 1.63 (not 2.x) gem install aws-sdk -v 1.63

after installation, please run the following to make sure all is in order:

rvm use ruby-2.1.5 (should simply say "using PATH/ruby-2.1.5)

gem list (should include the line "aws-sdk (1.63)")

then run irb, and type in "require 'aws-sdk'"

output should be "true"
