I added some paragraphs explaining the gist of how the database is structured to https://www.quaddicted.com/help/how_to_package_and_release_a_file#quaddicted_s_database
I also added a link to dumptruck_ds’ video https://www.youtube.com/watch?v=C-NGjpa8iYM
Anything that is unclear or misleading or in any other way improvable? The page is meant to be a good guideline to the best practice in terms of releasing custom Quake content.
In a perfect world this would be explained at https://quakewiki.org/ rather and cover best practices for all kinds of content. If you would like to expand it and nourish it there, please shout.
