This is explain how you would update a proper story on to this site. First of you should know how to add a page, if not then go to Help:Adding A Page. Once you know how to keep reading on.
Basically, to explain in a simplistic form. What you would need to do is create a page for EACH AND EVERY DIFFERENT CHAPTER. Do not put them all on one page. Once you have a some chapters ready to upload, simply make the pages and write them down. Then create a NEW page to store your chapters, that new page will be the one uploaded into the AS Bank. Below is an example of what it should look it in the AS Bank (These pages aren't real, don't create them.)
