You click on the page icon that is immediately to the right of the number of pages on this wiki that says "create a new page" when you hover over it with your mouse. Then you put in the title and copy-paste your finished work in the large box.

All that being said, I'd strongly recommend using the writer's workshop for feedback before then as your story will be deleted if it is not up to the site's quality standards.
