+;; Elpher aims to provide a practical and friendly gopher client
+;; for GNU Emacs.  It supports:
 
-;; - intuitive keyboard and mouse-driven interface,
-;; - caching of visited sites (both content and cursor position),
+;; - intuitive keyboard and mouse-driven browsing,
+;; - out-of-the-box compatibility with evil-mode,
+;; - clickable web and gopher links *in plain text*,
+;; - caching of visited sites,
 ;; - pleasant and configurable colouring of Gopher directories,
 ;; - direct visualisation of image files,
-;; - (m)enu key support, similar to Emacs' info browser,
-;; - clickable web and gopher links in plain text,
 ;; - a simple bookmark management system,
-;; - support for TLS gopherholes.
+;; - connections using TLS encryption.
 
 ;; To launch Elpher, simply use 'M-x elpher'.  This will open a start
 ;; page containing information on key bindings and suggested starting
 ;; points for your gopher exploration.
 
-;; Faces, caching and other options can be configured via
-;; the Elpher customization group in Applications.
+;; Further instructions can be found in the Elpher info manual.
+
+;; Elpher is under active development.  Any suggestions for
+;; improvements are welcome!
