Using RSS Feeds in Drupal?

Hi! I’m new to Drupal. Very new. I just started last week.

I need to filler content to start working with some of the features, and since many of our articles are going to come from RSS feeds, I thought I’d jump right in to that.

My question is how I can import from an RSS feed in Drupal? Let’s say I want to use this one: http://www.catholicnews.com/rss/cns-top-story.xml. What are the steps involved in setting this up so that these feeds generate articles based on the content every 30 minutes or so? Oh, and I put a custom data field on my articles for “Category” so I can specify which category these articles are supposed to be.

I couldn’t really find a straight answer on Google (at least not that I could understand) so maybe I’m approaching this incorrectly.

Thanks for any help you can offer!
