You should see several Pathfinder logos on the left of your screen. Click the Pathfinder Society logo. After that there is a link in purple colored font under the introductory paragraphs that says "Join and create your character."
Basically all you need is a Pathfinder Society number and a character created out of a 20 point build which is explained on page 16 of the Core Rulebook.
I hope that helps.
