This blog article is written using OnePile. It is just a simple note created in the app that has been exported as Markdown to feed a simple static site builder. Also the help has been created using this approach.
While doing this I learn more and more about the requirements of the application. I also immediately feel the pain when something essential is missing and also in the same moment have a test case to check the improvement.
