+## Deploy Hermes Instead of OpenClaw
+
+This launchable provisions the OpenClaw runtime by default.
+The deployed agent is selected from the `NEMOCLAW_AGENT` environment variable that the launchable passes to the installer:
+
+- When `NEMOCLAW_AGENT` is unset, the installer defaults to `openclaw`, and the **Launch** page shows `RUNTIME = OpenClaw`.
+- When `NEMOCLAW_AGENT=hermes`, the installer provisions the Hermes (NemoHermes) runtime, and the **Launch** page shows `RUNTIME = Hermes`.
+
+To deploy Hermes through the Brev web UI, the launchable's startup environment must export `NEMOCLAW_AGENT=hermes` so the installer selects Hermes, matching the documented Hermes installer entry point:
+
+```bash
+curl -fsSL https://www.nvidia.com/nemoclaw.sh | NEMOCLAW_AGENT=hermes bash
+```
+
+If a Hermes-targeted launchable does not set `NEMOCLAW_AGENT=hermes`, it silently falls back to the OpenClaw runtime even though Hermes was requested.
+For the terminal-driven Hermes flow, see the [Quickstart with Hermes](../get-started/quickstart-hermes).
