# Overwriting application.rb If you need to extend or modify the `config/application.rb` just do it at the `config/application_custom.rb` file. For example if you want to change de default language to English, just add: ```ruby module Consul class Application < Rails::Application config.i18n.default_locale = :en config.i18n.available_locales = [:en, :es] end end ``` Remember that in order to see this changes live you'll need to restart the server.
