-'fiv' is an image browser and viewer, supporting BMP, PNG, GIF, JPEG, WebP
-directly, plus optionally raw photos, HEIC, AVIF, SVG, X11 cursors and TIFF,
-or whatever gdk-pixbuf loads.
-
-Its development status can be summarized as '`beta`'.
-E.g., certain GIFs animate wrong.
+'fiv' is a slightly unconventional, general-purpose image browser and viewer.

-Non-goals
----------
- - fancy UI--the focus is on speed of use first, colour accuracy second
- - editing--that's what _editors_ are for, be it GIMP or Rawtherapee;
-   nothing beyond the most basic of adjustments is desired
- - memory efficiency, though preloading can cause some pressure
- - portability to non-UNIXy systems
+Features
+--------
+ - Uses a compact thumbnail view, helping you browse collections comfortably.
+ - Supports BMP, (A)PNG, GIF, JPEG, WebP directly, plus optionally raw photos,
+   HEIC, AVIF, SVG, X11 cursors and TIFF, or whatever gdk-pixbuf loads.
+ - Employs high-performance file format libraries: Wuffs and libjpeg-turbo.
+ - Makes use of 30-bit X.org visuals, whenever it's possible and appropriate.
+ - Has a notion of pages, and tries to load all included content within files.
+
+Explicit non-goals
+------------------
+ - Editing--that's what _editors_ are for, be it GIMP or Rawtherapee;
+   nothing beyond the most basic of adjustments is desired.
+ - Following the latest GNOME HIG to the letter--header bars are deliberately
+   avoided, for their general user hostility.
+ - Portability to non-UNIXy systems, although patches are welcome.
+ - Memory efficiency is secondary to both performance and development time.
+
+Aspirations
+-----------
+Show colours as accurately as hardware allows.  Open everything.  Be fast.
+Not necessarily in this order.
