-# RoboTwin archive layout
-
-This directory contains the RoboTwin data used by 4RC.
-
-Each task is stored as one uncompressed tar archive:
-
-    RoboTwin_random/<task>.tar
-
-Every archive contains:
-
-    <task>/<episode>/images/...
-    <task>/<episode>/depths/...
-    <task>/<episode>/intrinsics/...
-    <task>/<episode>/extrinsics/...
-
-Download and reconstruct the original RoboTwin directory:
-
-    from huggingface_hub import snapshot_download
-
-    local_dir = snapshot_download(
-        repo_id="HarrisonPENG/4RC-Action",
-        repo_type="dataset",
-        allow_patterns="RoboTwin_random/*.tar",
-    )
-
-Then extract all tar files into the same destination directory. The archives
-are not compressed because the source images are already PNG-compressed and
-uncompressed tar supports faster creation and extraction.
