-// In production, we register a service worker to serve assets from local cache.
-
-// This lets the app load faster on subsequent visits in production, and gives
-// it offline capabilities. However, it also means that developers (and users)
-// will only see deployed updates on the "N+1" visit to a page, since previously
-// cached resources are updated in the background.
-
-// To learn more about the benefits of this model, read https://goo.gl/KwvDNy.
-// This link also includes instructions on opting out of this behavior.
