+
+This add-on was inspired by the awesome add-on 
+[Custom Background and Gear Icon](https://github.com/AnKingMed/Custom-background-image-and-gear-icon). 
+However, it takes a different approach to the way the background images are set. 
+Among the advantages are:
+* The wallpaper is set for the entire window, including the menu;
+* The wallpaper is continuous—there’s only one per window;
+* The wallpaper doesn’t flicker when navigating between decks;
+* Dialogs can have wallpapers as well.
+
+There are also some disadvantages due to platform limitations:
+* You can’t resize the wallpaper along with the window;
+* It is not possible to control wallpaper opacity as easily.
+
+You will find configuration in _Tools_ → _Add-ons_ → _Config_, along with a short manual.
+After configuring the folder with your wallpapers, 
+you’ll be able to change the wallpaper via _View_ → _Next wallpaper_ 
+(on Anki 2.1.49 _Tools_ → _Next wallpaper_),
+as well as via the global shortcut <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>W</kbd>.
+You will have to manually resize the wallpapers to your preferred size,
+and if you need to change to opacity, you will also have to do it by hand. 
+Sorry about that.
+
+Note that by default Anki cards set their own background color in CSS.
+In order to see the wallpaper while reviewing, you must remove the card background.
+You can do so by going to _Browse_ → _Cards…_ → _Styling_ 
+and removing the line with `background` or `background-color`.
