Twine is an open-source tool for developing interactive, non-linear stories.
Download twine from their website or use it online at https://twinery.org/2
Give your story a title, don’t worry about the perfect title now. You can change it later.
Double-click the box in the center of your work area to begin typing the first passage of your story.
To link a passage, enclose the title of the new passage in double square brackets, [[title of passage]]. You can create multiple linked passages if you make a new line and put the second passage option in double square brackets as well.
If you want to make the link read something different from the title of the passage you can separate the link title from the passage title with a pipe, [[link title|passage title]].
