+## Important Note
+
+If you have an extension in your route, e.g. `foo.css` or `foo.com`, then the i18n middleware we expose (see below) will not effect this.
+
+We have considered accepting a pull request to handle detection of file extension (e.g. if it is a domain name) or another way to allow certain routes to bypass this.
+
+Thank you, and let us know if you have any issues!
