Imho, it would be simpler and more effective to create a forum topic here (e.g. “Detailed upgrade from 6.0 to 7.0”). This forum is the de facto source for Tryton information, and users with edge cases can add their own comments/experiences. Imho it is unrealistic for the Tryton project team as-is to provide the type of documentation you are requesting. However, and while not speaking for either the project team or foundation, I expect someone who wanted to specifically develop sysadmin and user documentation with the endorsement of the project team or foundation would not be turned away.
Regarding tryton.community (because I did not find a way to comment on tryton.community itself), statements such as ‘The team will be elected “somehow”’, and “members and contributors will decide on a more detailed governance as the project evolves.” without mention of how to become a member or contributor dilute the value of the site and discourage rather than encourage involvement.
Imho there is value and demand for the goals stated on tryton.community (“Our Service”). It is more likely to be successful by staying true to those goals, and also as soon as possible to formalize membership and governance, and to provide the infrastructure to deliver on those goals. Trying to also be a documentation site will take away from its’ value as a common repository for community modules and will also fragment Tryton documentation. Until the Tryton project or Tryton Foundation provides or endorses a community-led source of documentation, I suggest this forum is the best location for the reasons I already stated.
Fwiw, I’m in the progress of writing “Working with Tryton”, a book which takes a visual approach to explaining common user workflows using step-by-step screenshots. It will be released in beta form on trytoncloud.ca when the sales and purchasing workflows are completed (which should be by Christmas). The balance of the book will focus on manufacturing process, including BOMs and specifying part alternates. The completed book will continue to be available for free in digital form, which is only fair considering much of the content is or will be based on discussions here in the forum.
