SEO friendly root URL in Rails

routes.rb

Rails.application.routes.draw do
	# This isn't the best solution
	# if you want to get to the
	# root page and you do I18n,
	# because it adds a parameter
	# if you link to the root page.
	#
	# FormHelper Example: <%= link_to "Home", root_path %>
	# Result: http://example.com/?locale=en
	#
	# This isn't very SEO friendly.
	root 'welcome#index'
	
	# Better solution
	#
	# Example: <%= link_to "Home", i18n_root_path %>
	# Result: http://example.com/en
	#
	# Much SEO friendlier :)
	get ':locale' => 'welcome#index', as: :i18n_root
end
