Demos and statements of proofs-of-concepts are no documentation. Documentation needs to appear in the application, as well as on a dedicated website that has the same, and some additional information than what is included in the app.

This will not be done until the app is ready for primetime. And hopefully, it will be complete enough (an extension possibly), that a person who is unfamiliar to the app can easily reference it for needs.

Alpha version delibertly do not do documentation; its pointless as there can and usually are major changes before all coding is final (optimized).
