Further notes towards in-site documentation for Drupal

So, i was trying to decide whether to install the year-old alpha2 or the reasonably recent version of advanced help, as the structure to start building more robust documentation into the site (like, documenting the fact that user profile information will be selectable as a public contact). Why not just ask the current Drupal 8 maintainer of https://www.drupal.org/project/advanced_help if only we could find this mysterious “gnuget” character…

Update: So despite Agaric’s clear interest in, and proximity to, doing documentation with Drupal and within Drupal, we don’t have the answer— David isn’t actively working on the Drupal 8 version of Advanced Help, just reviewing what others put forth (not much currently).
