  4. wp-content/themes/parent/rss.php

For the needs of this tutorial, it’s best to set the slug to the kind of feed you’re creating (on this case: rss), and the identify to the feedname configured earlier on.

When you’ve informed WordPress to search for the feed template, you’ll have to create it. The under code will produce the format for the feed with the data we listed earlier. Save this file in your theme folder because the slug-name.php template file configured within the get_template_part operate.
