## Quick start

1. **Read** [docs/EMMC-PROVISIONING-GUIDE.md](docs/EMMC-PROVISIONING-GUIDE.md) for setup and usage.
2. **Proxmox:** Use [scripts/deploy-to-proxmox.sh](scripts/deploy-to-proxmox.sh) to deploy to a Proxmox host; see [docs/PROXMOX-LXC-DEPLOYMENT.md](docs/PROXMOX-LXC-DEPLOYMENT.md).
3. **Manual host:** Copy scripts from `host/` to the host and install the udev rule (see the guide).
4. Put **golden.img** in `/var/lib/cm4-provisioning/` (or your configured path). When a device is detected (USB or network), the **dashboard** asks **Backup** or **Deploy**.
