 **Q. But why?**
 
 A. Because I got bored one sunday morning, and I like Bing wallpapers.
+
+**Q. Names in the menu change but application does not change my
+wallpaper**
+
+A. This may be caused by one of three things:
+- You did not allow application access to System Events when it first
+  asked (you can change it under Preferences > Security)
+- Your current wallpaper setting is "Change wallpaper every ..." in
+  macOS preferences. Set wallpaper to static image to allow Beengpaper
+  to work
+- Application broke because something changed in Bing stream. If you
+  think your problem is not related to two above, pleas open an issue on
+  GitHub.
