 =============
 
-A CLI tool to set a wallpaper spanning over multiple monitors in sway.
+A simple CLI tool to set wallpapers spanning over multiple monitors in sway.
 
 It uses the Wayland output configuration to determine monitor size and position, and splits the provided image into separate images for each monitor. These are saved to `~/.cache` by default. It then uses `swaybg` to set the images on the corresponding monitors. To persist the changes the program outputs sway configuration lines which can be written to a sway configuration file.
