 ## Documentation
 
 When changing behaviour that is documented, update the related docs too: `README.md` (configuration, feature flags), `docs/`, `.env.example` and the Helm chart values.
+
+Screenshots in the Antora docs (`docs/modules/cockpit/images/`) are generated by the specs in `e2e/docs-screenshots/`. Regenerate them with `npm run docs:screenshots` after changing the UI they show. Add new screenshots as specs there, never by hand.
