The file app/sitemap.ts will automatically create a new sitemap with each deployment.

Of course, all of your products and all added pages (e.g. /about) will be added.

The file public/robots.txt contains the basic info for all search engine spiders. Within the implementation guide, there is one step to change the URL in this file as this cannot be done automatically.

The file app/manifest.ts will automatically create a Manifest.json that provides necessary info about the location of your icons.
