Chapters

This may be a dumb question, but I'm new to posting stories on this website. How do you make chapters? I have a three-part story I'd like to post, but I'm not sure how to get it to where I can do so in chapters. Any help would be greatly appreciated! :)

alright, in case you haven't figured it out yet, you'll see your username on the top right corner in green. click on that, and then go to my stories. now incase you don't have a story, there's an icon in red "new story". clock on that, and start putting in the title and summary as it says. now once you've done that, right, you have options right under the story to edit and all in green, and click on chapters and add them! hope it helped. :)
