@phuedx: Do you want to put the docs at https://wikitech.wikimedia.org/wiki/Test_Kitchen/GrowthBook_admin_guide (to complement https://wikitech.wikimedia.org/wiki/Test_Kitchen/GrowthBook_user_guide) or at https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Growthbook?

Let me know when you do because I want to dump some of my brain (e.g. data sources, experiment assignment queries) so we have docs of how that stuff works.

That would be perfect. I've finished up my draft rewrite of the Architecture page, including how GrowthBook has been slotted in. Though I'm reviewing and planning on working on https://wikitech.wikimedia.org/wiki/Test_Kitchen/Troubleshooting at the moment, which I suspect will have some overlap with the GrowthBook admin guide page 🤔

I've added what I can. While working on this I noticed that we haven't configured GrowthBook to export metrics to Prometheus. I've raised T430118: [GrowthBook] Export metrics to Prometheus.
