How to block

I am making an scarf from a pattern called “undulating waves”. I am using the Dream in Color yarn that is 98% merino wool and 2% silver fibers. At the end of the pattern it says “block”. After a quick google search, I understand that blocking involves water, pins, and drying. Can anybody help me with a better understanding of how to block a scarf, including how much water should be involved with the yarn I am using (completely wet, spray).

Thanks for any ideas!
