+Most of the magic happens in the build.py script, where you can set your own wallpaper and tile size. This script outputs a 1920x1080 64x64 tile `wallpaper.png`

 For the convinience of Windows 10 users (of which I am one) I have packaged build.py up into build.exe, which should *just work* for you.
 
+You can get the latest build.exe by heading over to the release page here: https://github.com/Gadgetoid/wallpaper/releases
+
 On Windows 10 I use WallpaperChanger.exe to change the wallpaper from the command-line, it has been included for convinience.
