Add software short cut

I have a program that did not add a shortcut to my menu . only way I can not start it is unless I open the ter . How do I add a shortcut to the menu for the program ?

Hit the SUPER/WINDOWS key on the keyboard. Type the name of the app, right click it, and add to favorites. Its the quickest way to get the icon added to your panel, which is quicker access, then trying to click it from the menu.

the software was just unzip into a folder only

What software was it, and how did you download and install it?

I download and it is a gz file
