fedora: add script launcher to favorites bar

i recently installed viber on my fedora 20 box. i initially made it to start when i log into my account but i realized i rather want to manually launch it.

first you have to make your script an application launcher:
create a file in /usr/share/applications/<app_name>.desktop with the ff contents:
[Desktop Entry]
Type=Application
Name=<app_name>
Comment= "<comment>"
Icon=<path_to_image>
Exec=<script_to_execute>
Terminal=false
Categories=<category>

here's what's in my /usr/share/applications/viber.desktop file:
[Desktop Entry]
Type=Application
Name=Viber
Comment= ""
Icon=/home/user/Viber/Viber_icon.png
Exec=/home/user/Viber/Viber.sh
Terminal=false
Categories=Communication

then search your app in your desktop's search field (point mouse to upper left corner then type name); your launcher should now appear and you can do a right click on it and select "Add to Favorites"
