Example on signing a LKM?

Hi Greg (or anyone who can advise), I have been browsing on: https://kernel.googlesource.com/pub/scm/linux/kernel/git/dhowells/linux-mods... I heard that the CONFIG_MODULE_SIG has to be turned on, but it was not stated particularly how. I am also not sure how to use a kernel make command. I also found this http://unix.stackexchange.com/questions/74022/sign-a-module-after-kernel-com... but cannot piece together enough to run a mini signed LKM. Would you guide me on a minimallist example on signing a helloworld LKM? Thank you, Greg. Sincerely, Michael
