how to add multiple packages to build debian-live using live-wrapper

The only manual I could find is [readthedocs](http://live-wrapper.readthedocs.io) . So far I have understood the following: 1. I have to start working in a dedicated directory 1. It needs the latest debian-archive-keyring not necessarily provided by other debian based OS 1. -d is distro -m is mirror server -e is package to be installed with only dependencies -t is package installed with recommendations and -f is installed firmware packages Did I get it right? Also I couldn't pass more then one package in either of the parameters. Could anyone lead me to the right direction? My command so far goes like this: lwr -d bullseye -m http://mirror.xeonbd.com/debian/ -e kde-full -t debian-installer-launcher -f firmware-realtek I haven't used either live-wrapper or live-build before.
