# Hugging Face Docker Space Deployment Steps — v3.3.1

1. Create a new Hugging Face Space.
2. Choose **Docker** as the SDK.
3. Keep it private for first testing.
4. Upload the extracted contents of this packet to the repository root.
5. Add Space secret:

```text
SUBSTRATE_ACTION_KEY=<long random secret>
```

6. Build the Space.
7. Open:

```text
https://YOUR-HF-SPACE.hf.space/v1/mesh/health
```

8. Confirm `status` is `HELD` and `auth_configured` is `true`.
9. Test `/v1/mesh/command` with the same Bearer token.
10. Only after that, connect GPT Actions.

Do not place the bearer token in README, Knowledge files, OpenAPI YAML, or public code.
