I just recently started clipless myself (about three days ago). I got M520 and a Specialized MTB shoe. I was told to lower the tension all the way and put the cleat in the most middle position from a friend of mine. I didn't care if I fell or not, so I just got on my driveway, clipped in, and told myself to unclip before I got to the sidewalk. It was pretty simple and I also don't understand why many assume it is a long process. I am currently having problems with fit though. I did a longer ride (about 25 miles) and noticed a slight pain around the sides of my kneecap. I raised my seat about a centimeter or two and am now playing with the cleat position. It has been super frustrating for me.
