I was quite surprised after installing SongKong on my Linux desktop that it didn’t set itself up with a launcher, integrated into the menu system. I found it tiresome, every time I wanted to run SK, to have to open a terminal, cd to the songkong folder and run the songkong.sh script.
I’m a user, not a developer, so I asked for help on one of the forums and now I have an icon for SongKong in my Applications menu and can launch it from that like any other app. Here’s a link to the forum thread where I learned how to do it. Although the discussion pertains to Manjaro Gnome Linux, it should be adaptable to other distros.
