+# T-Shirt Folding Mixed Manifest
+
+This repo is a lightweight manifest for a public T-shirt folding collection built from five source datasets:
+
+- `Gongsta/trlc_tshirt_folding`
+- `Gongsta/trlc_tshirt_folding_impedance`
+- `Gongsta/dagger_dk1_tshirt_corrections`
+- `Gongsta/krish-simpler-tshirt`
+- `Gongsta/e7-tshirt-folding`
+
+The goal is to provide one clean public entrypoint while preserving each source dataset at its highest native frame rate.
+
+## What Is In This Repo
+
+Each row in `data/train.jsonl` describes one source dataset and includes:
+
+- `source_repo`
+- `source_tag`
+- `native_fps`
+- `is_dagger`
+- `is_impedance`
+- `scene_type`
+- `shirt_layout`
+- `recommended_common_fps`
+
+This repo does **not** duplicate the source videos. It is a manifest / collection layer that documents provenance and intended loading behavior.
+
+## Source Tags
+
+- `apartment_original_multi_shirt`
+- `apartment_impedance_multi_shirt`
+- `multi_shirt_dagger_corrections`
+- `apartment_single_shirt`
+- `building_single_shirt`
+
+## Recommended Loading
+
+If you want to combine all five datasets with exact-stride downsampling and no interpolation, use:
+
+- `target_fps = 10`
+
+Why:
+
+- `30 -> 10` is exact stride `3`
+- `50 -> 10` is exact stride `5`
+
+If you want to keep native FPS, load the listed source repos directly and treat this dataset as the metadata / provenance index.
+
+## Notes
+
+- `Gongsta/trlc_tshirt_folding` is the only `30 Hz` source.
+- `Gongsta/dagger_dk1_tshirt_corrections` is the DAgger dataset and is `50 Hz`.
+- The other listed sources are `50 Hz`.
+
+## Example
+
+```python
+repo_ids = [
+    "Gongsta/trlc_tshirt_folding",
+    "Gongsta/trlc_tshirt_folding_impedance",
+    "Gongsta/dagger_dk1_tshirt_corrections",
+    "Gongsta/krish-simpler-tshirt",
+    "Gongsta/e7-tshirt-folding",
+]
+
+# For an exact-stride common timebase across all five:
+target_fps = 10
+```
