+      #
+      # Second, it'll scope the key by the current partial if the key starts with a period. So if you call translate(".foo") from the
+      # people/index.html.erb template, you'll actually be calling I18n.translate("people.index.foo"). This makes it less repetitive
+      # to translate many keys within the same partials and gives you a simple framework for scoping them consistently. If you don't
+      # prepend the key with a period, nothing is converted.
