• If you haven't already, go setup Ruby with chruby + ruby-install
• Save your hair by setting up auto-switching with chruby
• Add a .ruby-version file with Ruby version you want to use: 2.2.1
• Add a .powenv file with:

source /usr/local/share/chruby/chruby.sh
chruby $(cat .ruby-version)

• Generate the rails app skeleton: $ rails new my_billion_dollar_app
• Link it up to pow: $ ln -s ~/Sites/my_billion_dollar_app ~/.pow/.
