This document provides instructions for finding and using RSS feeds. It explains that RSS feeds are used by ZootRock to deliver updated content from websites into custom streams. It recommends not using Safari to find RSS feeds and instead provides steps for other browsers like Chrome and Firefox to view a website's source code to locate an RSS feed link. The instructions describe adding "/rss" or "/feed" to website URLs or using the browser's search function to find the RSS feed within the source code.
