Rails Internationalization (I18n) API — Ruby on Rails Guides

The Ruby I18n (shorthand for internationalization) gem which is shipped with Ruby on Rails (starting from Rails 2.2) provides an easy-to-use and extensible framework for translating your application to a single custom language other than English or for providing multi-language support in your application. The process of "internationalization" usually means to abstract all strings and other locale
