+# DROID episodes
+
+Publication status: **uploading — do not use yet**.
+
+33,966 episodes in 1,018 uncompressed TAR shards. Episodes are ordered lexicographically by folder name; no episode spans shards.
+
+All original file contents and directory names are preserved, including RGB, depth, TCP, actions, observations, calibration and metadata. TAR ownership, permissions and timestamps are normalized. No image/video re-encoding is performed.
+
+Use `episodes.jsonl` to map episode IDs to shards and filter language instructions, lab, status or frame count. `shards.jsonl` provides byte sizes and SHA-256 hashes. Each TAR extracts to original episode directories. A subset requires only its corresponding shards, but each selected shard is downloaded in full.
+
+Download `droid_hf.py` and `requirements-droid-hf.txt` from this repository. With Python >= 3.10, install the requirements and run:
+
+```bash
+python droid_hf.py download --repo-id OWNER/DATASET --shards 0-2 --output-dir ./episodes
+python droid_hf.py download --repo-id OWNER/DATASET --episodes-file ids.txt --output-dir ./episodes
+```
+
+The download command verifies and extracts one shard at a time. It removes verified local archives after extraction unless `--keep-archives` is set. Existing differing episode directories are never overwritten.
