Different url segment for the homepage

<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

how do I change the http://tttt.com/home to something different like http://tttt.com/custom-home-page-segment

Director::addRules(100, array( 
   '' => '->testing', 
));

I found this on old forum which may work for SilverStripe 3 but doesn’t work in 4. Any ideas guys.
