A Google Sitemap is very useful for SEO and often required. TYPEMILL creates a google sitemap out of the box and stores it in the cache folder. You can find the url for the sitemap in the system settings (basically it is something like
https://yourwebsite.net/cache/sitemap.xml). Simply add the url to the google search console and you are done. The sitemap will update once a day. You can also trigger a manual update with the F5 key (Windows).
