 - `pds.env` is Ansible-managed. Secrets (JWT, admin password, PLC rotation key) are generated by the installer on first run, then read and preserved by Ansible on subsequent runs. To change config like S3 or SMTP, update `vars/main.yml` and re-run the playbook.
 - The installer creates a `pds.service` systemd unit. It's left in place — it just runs `docker compose up -d` on boot. Docker's `restart: unless-stopped` policy also handles this independently.

+**Variables** (non-sensitive config):
+
+| Variable | Description |
+|---|---|
+| `SERVER_IP` | Target server IP address |
+| `PDS_HOSTNAME` | Public DNS name for the PDS (e.g., `pds.example.com`) |
+| `PDS_ADMIN_EMAIL` | Admin contact email |
+
+**Secrets** (sensitive credentials):
+
+| Secret | Description |
+|---|---|
+| `SSH_PRIVATE_KEY` | Private SSH key for the `sysadmin` user on the target server |
+| `OVH_S3_ACCESS_KEY` | OVH S3 access key for blob storage |
+| `OVH_S3_SECRET_KEY` | OVH S3 secret key for blob storage |
+
+The workflow installs Ansible, writes the SSH key from a secret, generates `inventory.yml` and `vars/main.yml` from vars and secrets, and runs the playbook.
