+Note that certain programs may use different naming schemes for their .desktop
+file compared to the main executable.
+To ensure that both files are handled in the same manner, it is recommended to
+list both names in the configuration.
+For example, if Spectacle has its main executable at /usr/bin/spectacle and its
+\&.desktop file at /usr/share/applications/org.kde.spectacle.desktop, then the
