Unity - Adding Applications to Launcher if they don't get recognised automatically

When I installed Open Office Unity didn't 'see' it. I had to launch it using a terminal. To get it to show up when you search and so you can pin it to the launcher make a file with a .desktop extension as follows:

[Desktop Entry]
Version=1.0
Name=NAME OF APPLICATION
Comment=WHATEVER YOU WANT TO SAY ABOUT IT
Exec=PATH TO EXECUTABLE
Icon=PATH TO ICON
Terminal=false
Type=Application
Categories=Application;

Put the file in your home directory under .local/share/applications, It will then show  up when you search for it. If you want to add it to the launcher fire it up then right click on the icon on the launcher and 'Add to Favorites'
