Yes, indeed congratulations on the solo sail! That feeling of independence is quite a rush! Brings back memories of my first serious single handed sail. At its successful conclusion I felt nineteen feet tall, I didn't care if it meant anything to anyone else, it meant something to me. As I'm sure yours does to you.
A couple thoughts:
Although everyone does it different, for me instead of the pdf I learned to be "at home" in my harness. When alone, under sail or power, at sea or local sailing I have my harness on. And if I'm beyond the companionway I'm tethered to a wire that runs the full length of the cockpit forward to the mast where it splits to two wires, one each side of the dinghy. I don't need the PDF if I don't part company with the boat. Fine or foul weather the harness is on and I'm tethered if I'm beyond the companionway. Only once did I forget/neglect to hookup and that once almost cost me my life. A self steering boat doesn't really care if one is aboard or not.
Although the harness does make for funny tan lines.
