 #### A convenient way to set up, manage and use localized routes in a Laravel app.
 
 - [Automatically register](#register-routes) a route for each locale you wish to support.
+- Use [route slugs or custom domains](#supported-locales) (or subdomains)
 - Optionally remove the locale slug from the URL for your main language.
 - [Generate localized route URL's](#generate-route-urls) in the simplest way using the `route()` helper.
 - [Redirect to localized routes](#redirect-to-routes) using the `redirect()->route()` helper.
 - Allow routes to be [cached](#cache-routes).
-- Let you work with routes without thinking too much about locales.
 - Optionally [translate each segment](#translate-routes) in your URI's.
