# Backup

Previous full versions of the project READMEs, kept before the documentation was
rewritten (2026-08) to focus only on the currently used workflows
(GELLO teleop and manual drag).

- `README_old.md` — previous English README (Pika / UMI / SpaceMouse / demo videos, etc.)
- `README_ZH_old.md` — previous Chinese README

The backups are verbatim copies of the files as they existed at commit `b5d46c4`
and can be restored with:

```bash
cp backup/README_old.md README.md
cp backup/README_ZH_old.md README_ZH.md
```
