Question: How can you implement internationalization in Ruby on Rails?

Ruby ships with i18n which is an internationalization gem. 

You need to create locale files and save them under the config/locales directory as:

en.yml

es.yml

fr.yml

The keys should match for each of these files. 

en:   main_page:     hello: “Hello”     welcome: “Welcome to   My Company” es:   main_page:     hello: “Hola”     welcome: “Bienvenido a Mi Empresa” fr:   main_page:     hello: “Salut”     welcome: “Bienvenue �  Mon Entreprise�

� In your code you would need to specify that the text would be locale specific. So change it to something like this:

.content   %h1     = t("main_page.hello")  
 %p     = t("main_page.welcome")

Then you have to select the actual locale.
