+// fern is a simple media feed downloader.
+//
+// It depends on yt-dlp to download the media found in the media feeds
+// to your computer.
+//
+// fern currently supports YoutTube and NPR feeds.
+//
+// Information about what media feeds to download, the location of
+// yt-dlp program on your computer, and the directory where the media
+// should be downloaded to must be specified in a config file which
+// fern expects to be at $HOME/.config/fern/fern.json
+//
+// fern's config file contains three fields:
+//
+// {
+// "ydl-path": "/usr/local/bin/yt-dlp",
+// "dump-dir": "~/media/feeds", // media feed download directory
+// "feeds": [...] // list of media feeds.
+// }
+//
+// Each item in the media "feeds" must be:
+//
+// {
+// "id": "media-feed-id", // uniquid identifier for the media feed
+// "source": "https://feeds.npr.org/XXXX/rss.xml", // media feed url
+// "schema": "npr", // should be "youtube" or "npr"
+// "last": 5 // The last N items that should be downloaded
+// }
+//
+// You may download an example config file for fern from
+// https://ricketyspace.net/fern/fern.json
+//
+// fern does not take any arguments, to run it just do:
+//
+// $ fern
