How browsers understand for a Website RSS feed

Once the RSS feed is created in feed.xml, You have to tell the browser.

One way, using a link tag.

<link rel="alternate" type="application/rss+xml"
  href="https://www.w3schools.io/rss.xml" title="Your title">

Another way, using robots.txt with a sitemap field

Sitemap: https://www.w3schools.io/rss.xml
