Spree is a fantastic eCommerce Rails-Engine. To change it, to speak German, one has to:
# Gemfile
# original repository not compatible at the moment, use fork
#gem 'spree_i18n', :git => 'git://github.com/spree/spree_i18n.git'
gem 'spree_i18n', :git => 'git://github.com/kares/spree_i18n.git'
# sh
bundle
rake spree_i18n:update_default
rake spree_i18n:sync
wget https://github.com/svenfuchs/rails-i18n/raw/master/rails/locale/de.yml -O config/locales/rails_de.yml
# config/initializers/spree.rb
if Spree::Config.instance
Spree::Config.set(:default_locale => 'de')
end
this should get you started
