Don't touch the seeds at all. Use a tweezer. You can't really do it wrong but....
I have found it is faster to put them in a very wet towel roll them up, put them in a plastic bag, put the plastic bag somewhere pitch black, and at least room temperature, maybe a couple degrees extra will trigger them a little faster. I have found that seeds
grow pretty much no matter what if you give them enough time. Plant the seeds as soon as they crack though to help stop root damage.
