Pretty Basic - How do I even add my 650 as a presence device?

Win app does not seem to have any marketplace icon for me to follow per the instructions. I have no idea how to even get my phone into the system as a presence device in the first place.

Put this out there and prepared to look like a total idiot, but hey… WP app looks very poor.
