No HELP in package

Hi, please add Help file with options. I have 19 gpus and I can't figure it out how to mine on all of them.
I tried with -d0 / -d01234 / -d0,1,2,3,4 and so on...many combinations, but the miner starts to mine always on gpu #0

I tried the .exe with -h -help and /h for any help.

Sorry, but for a newbie there's a pain in the ass to find the correct info and get it run.

Thanks a lot!
