I found this tool on Github and I personally think it’s way easier for noobs like me to get an appimage running.
Hello @xeno-idaltu, welcome to AppImage.
“Noobs” should not try to make their own AppImages, but ask the author of an application to provide an officially made (and supported) AppImage of the application.
Making a properly working AppImage requires some understanding of how the application works, and a “noob” doesn’t usually have this.
