-A wayland wallpaper tool with support for Gnome dynamic wallpapers.
-The main motivation behind `enkei` is to display dynamic wallpapers compatible with the
-Gnome wallpaper specification.
+`enkei` is a wallpaper tool created to allow displaying dynamic wallpapers based on the specification format used for example in the `Gnome` desktop environment.
+It is designed to offer a _smooth_ transition between wallpapers and gradual change over long and short periods of time.
+For a fast handling `enkei` uses `OpenGL` to render images and blending them for transitions.

+Writing a wallpaper tool is nothing new so there are other projects which are similar.
+There are already solutions for [animating GIFs](https://github.com/vilhalmer/oguri), [videos](https://github.com/GhostNaN/mpvpaper), [timed](https://github.com/xyproto/wallutils), and [static](https://github.com/swaywm/swaybg) wallpapers in Wayland.
+But the use cases were quite different from what I wanted or I wasn't happy with their handling of animations, so I started writing `enkei`.

 ## Feature Ideas
   
 - [ ] Allow setting of wallpapers via IPC
 
     > A nice to have would be to send messages to the already running enkei
-    > instance to change the wallpaper shown.  For this we would need to
-    > interrupt any ongoing animations or static images and hot-swap the images
-    > in the current gtk session.

 - [ ] Individual wallpapers on different displays
 
     > The base functionality for this is already present, as each output is
