Consult with this tutorial in order for you to utilize any syndication feed as an automated content and news source at your HTML site, by adding Autodiscoverability directives to HTML metadata.

While any of codes of this tutorial would work, it is recommended to use the code with the proper "type" attribute in respect to the type of feed which you want to add; and attribute "title" may be customized as you desire.

You are not limited to your ActivityPub, OStatus, or XMPP accounts, and you can also add any source of any other account and type.
