-For native JevalKit evaluation, use `python -m jevalkit prepare <benchmark>` to prepare local manifests and official scoring inputs. Pinned sources, protocols and checksums are maintained in [JevalKit’s data inventory](https://github.com/Liuziyu77/JevalKit/blob/main/docs/data-manifest.json).
+Download the ready-to-use TSVs with `hf download Valen-Team/JevalKit_Datasets --repo-type dataset --include "datasets/*.tsv" --local-dir "$JEVALKIT_DATA_ROOT"`. JevalKit reads pinned sources, protocols and checksums from its bundled [dataset catalog](https://github.com/Valen-Team/JevalKit/blob/main/jevalkit/datasets/catalog.json); no local manifest or conversion is required. Visual media and Decision Index scoring inputs have separate downloads in the [usage guide](https://github.com/Valen-Team/JevalKit/blob/main/docs/quickstart.md#download-data).
