Automatic RSS?

Thank you so much. Do you know if there is a way to post which site the feed is coming from?

It’s a little over my head. It says post this:

<cite class=”feed”>from <?php the_author_posts_link()?><?php
if (is_syndicated() and (get_the_author() !== get_syndication_source())):
echo ‘ @ ‘;
the_syndication_source();
echo ‘‘;
endif; ?></cite>

In the template for the theme but where?
