+#### Improved RSS Feed
+
+Some enhancements have been made to Hugo's [internal RSS](https://github.com/gohugoio/hugo/blob/25a6b33693992e8c6d9c35bc1e781ce3e2bca4be/tpl/tplimpl/embedded/templates/_default/rss.xml) generation code.
+
+**A page's cover image now appears at the top of its feed display**. This image is set manually using [the cover params](#how-to-add-a-cover-image-to-your-posts). If unset, the RSS generator searches for the first image file in the page bundle whose name includes 'featured', 'cover', or 'thumbnail'.
+
+**You can optionally display the full page content in your RSS feed** (default is Description or Summary data from Front Matter). Set `rssFullText = true` in your `config.toml` file to enable this option.
+
+**You can choose a site image to be displayed when searching for your RSS feed.** Set `rssImage = "image/url/here"` in your `config.toml` file to enable this option.
+
 ## How to start
 
 You can download the theme manually by going to [https://github.com/panr/hugo-theme-hello-friend.git](https://github.com/panr/hugo-theme-hello-friend.git) and pasting it to `themes/hello-friend` in your root directory.
