+# NOMAD Hawser Agent
+
+- **Repo stack path:** `/home/fizzlepoof/repos/truenas-stacks/infrastructure/hawser-nomad`
+- **Suggested live stack path:** `/opt/hawser-nomad`
+- **Dockhand environment:** existing `NOMAD` Hawser Standard environment on PD
+- **Why Standard mode:** NOMAD is on the LAN with a stable IP, so Dockhand can connect directly without the extra Edge-mode WebSocket plumbing
+
+Bring-up:
+
+```bash
+cd /opt/hawser-nomad
+cp .env.example .env
+bash bin/prepare_nomad.sh --up
+```
+
+Notes:
+
+- Use the Hawser token already configured in Dockhand's `NOMAD` environment.
+- Hawser listens on port `2376` by default, matching the existing Dockhand environment entry.
+- `STACKS_DIR` is bind-mounted to the same host path inside the container so Dockhand can deploy stacks that use relative bind mounts.
+- This is a standalone NOMAD deployment under `/opt`, not part of the core Project N.O.M.A.D. managed stack.
