# Raise an error when there is a route with uppercased letters in router.js (no-capital-letters-in-routes)

When you accidentally uppercase any of your routes or create uppercased route using ember-cli the application will crash without any clear information what's wrong. This rule makes it more obvious, so you don't have to think about it any more.
