# Connect Hermes Desktop

> Point the Hermes Desktop app at an instance over SSH.

Hermes Desktop drives your instance over SSH. Set up [SSH access](/docs/agents-api/ssh) once:

```bash theme={null}
npm install -g agent37
export AGENT37_API_KEY=sk_live_...   # https://www.agent37.com/dashboard/cloud/api-keys
agent37 ssh setup
```

Then in **Settings**, **Gateway**, pick **Connect via SSH**:

| Field           | Value                       |
| --------------- | --------------------------- |
| Host            | `<instance-id>.agent37.app` |
| User            | `node`                      |
| Everything else | Leave blank                 |

Click **Test SSH**, then **Save and reconnect**. Done.

If **Test SSH** fails, the instance is stopped, on an old image, or not running Hermes: [start](/docs/agents-api/instances#start) or [update](/docs/agents-api/instances#update) it and retry.
