Hey @JosW,
thanks for your feedback. While people do post obscure problems with their Nix setup (and often don’t get answers because they are too specific even for veterans), absolute beginner questions are very welcome and usually greeted with friendly replies on short notice.
In fact, for the forum regulars it is much easier to answer basic questions by linking to authoritative resources or explaining best practices than dealing with intricate technicalities of special cases. It also helps raise awareness of these basic issues, and would help direct how to improve the material and its discoverability - ideally by leveraging the curiosity and energy of those beginners, enabling them to contribute directly.
So by all means, please continue asking questions, even if they appear to sound naive. Those are actually the best.
Note though that development, marketing, and documentation efforts are currently focused on serving the needs of software developers, simply due to time constraints and the fact that this is already the largest fraction of users. In the same vein, the attempt to improve the learning experience is emphasizing Nix instead of NixOS. There is still a very active subgroup of NixOS enthusiasts, but I think we can expect more activity around Nix than NixOS in the near future.
