Hey, I'm Kolby. You had asked about how to begin writing stories. It's pretty simple, really. When you first open the app, there should be five different picture icons at the bottom like a home, a book shelf, etc. I want you to look for the pencil icon and click it. That will bring you to a page where it will say either create a new story or update an existing one (I doubt it'll have that second one). So yes, just click on new story, and it'll take you to the template to write your first work.
Thanks for coming to me, and if you need any more help, dm me, and I'll help wherever I can.
