Part of the process to explain how something works is to show the progress of creating it. That is why Poet provides a Git like experience where we can commit changes. Every commit is a de facto part of our Story. There is a nice markdown editor and UI for organizing commits. Deciding weather if they have to be included in the Story and their exact order.
If you are curious about all these stuff consider creating your own story or quickly scan the documentation. I hope you'll join me here in writing and sharing code novels.
