-## Recommended Local Preparation Flow
-
-After cloning or downloading this dataset, point the preparation
-wrapper at the bundled manifest:
-
-```bash
-bash scripts/prepare_finetune_dataset.sh \
-  --input-jsonl /path/to/b150_official_test_100/selected_samples.exported.jsonl \
-  --text-field target_text \
-  --audio-root /path/to/b150_official_test_100/raw \
-  --output-dir /path/to/prepared_b150_official_test_100
-```
-
-Notes:
-
-- The manifest stores paths relative to `raw/`, for example
-  `audio/EN/...` or `audio/ZH/...`.
-- The current split contains `44` English samples and `56` Chinese
-  samples.
-- The `duration` field is included in the manifest, so local dataset
-  preparation does not depend on Arrow metadata.
