We are moving into that direction. Let me explain…
One focus of marketing team is to present information on the website in a way that it can be easily discovered. Be it documentation or something else. But as we can agree documentation is something very important in a project like Nix.
While there is no documentation team currently there is quite a lot of different efforts in regards to documentation. We could wait for RFC 64, where a format / tools are being discussed, to be resolved or we can also move ahead and produce the content that we think is missing for newcomers. This will come in form of guides / tutorials (eg. Build docker images with Nix, …).
Hope this answers some of your concerns. What I think is important that we move step by step (eg. tutorial by tutorial) otherwise the size of the effort needed will wear us down.
