+# Deployer host baselining
+
+**Status:** Outline from approved design POR. Procedural scripts at **build**.
+
+## Purpose
+
+Create a clean host that can run the Docker-based Lumina stack. This product is **repo-driven**, not tied to one developer’s existing Hermes install.
+
+## Requirements (POR)
+
+| Item | Spec |
+|------|------|
+| OS | Linux x86_64 or arm64 (cloud VM, bare metal; WSL2 optional path only) |
+| Resources | Multi-core CPU; ≥8–16 GB RAM recommended; disk for Docker images |
+| Privileges | User able to install Docker / run Compose |
+| Network | Outbound HTTPS to model endpoint, SaaS APIs, MCP remotes, image registry |
+| GPU | Optional; only if local VLM is used (not required if vision is remote) |
+
+## Steps (operator)
+
+1. Provision host (cloud console / hypervisor).  
+2. Install base OS updates.  
+3. Create deploy user; clone this repository.  
+4. Run `./scripts/bootstrap.sh` (installs Docker if missing — when implemented).  
+5. Continue with [INSTALL.md](INSTALL.md).
