While Toolforge docs for both admins and end users exist on Wikitech, there is currently no high-level overview of the system architecture as a whole.
The primary audiences of this documentation would be:
- New technical volunteer contributors
- New engineers onboarding to WMCS
- Anyone (technical) at WMF who would like to understand Toolforge at a glance
@aborrero has already created a stub for this here: https://wikitech.wikimedia.org/wiki/Portal:Toolforge/Admin/System_Overview
