adding rss to my site

good morning everyone…i’m still up trying to figure out a bunch of stuff, specifically RSS.

i need to incorporate RSS into our wordpress site: https://www.paintlessbusiness.com/wordpress/

i’m new to all this rss stuff and when i read instructions on it about feeds and which applications to pick etc…i get lost.

can someone tell me not what an RSS is but how i can insert RSS into my already existing wordpress site?

thanks so much …

drew
