+## Description
+
+This plugin creates a limited number of posts of type RSS Item by importing items from an RSS or Atom feed. The post title, excerpt, content, featured image and publication date are taken from the feed item. You can have one or more feeds. The plugin fetches new items at a time interval you specify for each feed. For each feed, there is a limit that you set for how many posts it should contain. The plugin automatically deletes the oldest posts that do not fit within this limit.
+
+The point of importing feed items into posts is that they can all be displayed in the usual way in WordPress, e.g. with the block editor's query loop block.
+
