 **Adding new configs**: Create the YAML file, run `make validate`, then run the generated tests. No dedicated spec file is needed.
 
+The fetch suite has two lanes:
+
+- `make test-fetch-all-configs` runs all `:fetch` examples. Configs marked as Browserless-backed are skipped unless Browserless env vars are configured.
+- `make test-fetch-browserless-configs` runs only the Browserless-backed config subset and requires `BROWSERLESS_IO_WEBSOCKET_URL`. Custom endpoints also require `BROWSERLESS_IO_API_TOKEN`.
+
 **Config folder convention**: Place configs under the registrable domain folder (e.g., `example.com/` or `bbc.co.uk/`). Legacy subdomain folders (e.g., `news.example.com/`) are allowed but not preferred.
