There’s sentiment here on HN that any documentation is good documentation - and while it is better than NO documentation, it’s just not correct to dismiss truly great documentation.
For example, Stripe (the workplace of the author) has incredible documentation that single-handedly enabled me to build with it, despite my being a wretched server-side developer.
That the documentation alone doubled the potential user-base, thus fostering growth and engagement with the product, is a testament to the power of great document versus just documentation.
V1 docs in markdown - fine. But V2 for an ambitious tool should probably start approaching what Stripe is accomplishing.
