Podcasts

I'm really at a loss as to how I can add an RSS feed for a podcast. Someone's going to have to hold my hand to do this. There isn't enough information here for me to figure it out. If I were going to add a podcast to my iPod, I could probably do that but I'm not finding enough info for adding RSS feeds. I'm not sure podcast.com works at all either. Couldn't do anything in there.
