 # VLAC2 Benchmark Release
 
-This dataset repo contains the publishable VLAC2 benchmark bundle:
+This release contains:
 
 - `benchmark_json/`: ready-to-use benchmark JSON files for `train/` and the 4 test buckets
 - `scripts/`: frame extraction utilities
-- `_extracted_frames/`: generated frame root marker
-- `vlac2_release_data/`: placeholder raw-data tree; fill this with the original source datasets before extracting frames
-- `docs/`: simple usage notes
+- `vlac2_release_data/`: raw-data archives plus their manifest
+- `docs/`: minimal usage notes
 
-See `docs/vlac2_public_release.md` for the minimal end-to-end workflow.
+The release repo itself does not ship `_extracted_frames/`; the frame-extraction script creates that default output directory automatically when needed.
+Before frame extraction, first unpack all raw-data archives into `vlac2_release_data/`.
+See `docs/vlac2_public_release.md` for the end-to-end workflow.
