I am using Twine 2 in story format Harlowe 2.0.1
People have been asking about this a lot (and for years, now), so I put together a repository with all the code you'll need, an optional, simplified set of helper functions, and documentation and examples.

Edit.
Note that I just finished this. There might be bugs.
