Your Syndicate Module (sometimes called Syndication Feeds) will display a link that allows users to take a Feed from your website.
There are limitations though: your Syndicate Module will only display on pages for which Feeds are possible which means that this Module will not display on Single Article pages, Contact pages or Weblinks pages.
In Joomla, Modules are created and managed via the Administrator area.
