I think the way I do it is pretty easy.
Put seeds in a cup of tap water, and leave them there overnight and until they all sink to the bottom.
Then I cut a piece of white T-shirt (6x6 inches) Soak it in water, ball up the fabric in your hand and make a fist to squeeze out the water. Easy way to get the moisture right.
Fold it in half, put seeds in, Fold it again.
Put into a zip lock bag somewhere warm overnight and seeds will all be cracked with taproots pointing out.
Prepare my rockwool, or whatever you decide to use.
I then GENTLY put them about 1/8 to 1/4 deep into starter plug with the taproot pointing down.
Put the seed starters in ziplock bags, and I don't water after that. I usually see roots coming out within 2-3 days
Then it's time to put them into the system.
Pretty much a 100 percent success rate doing it this way.
You can do it however you want tho.
Hope this helps!
Peace.
