+# Services — Configuration & Runbook Index
+
+This directory documents all services operated by the Daystrom Institute. Each subdirectory contains deployment configuration notes, dependency maps, and links to operational runbooks.
+
+---
+
+## Service Catalog
+
+| Service Name | Stack | Host(s) | Runbook | Status |
+|--------------|-------|---------|---------|--------|
+| `<!-- service -->` | `<!-- stack -->` | `<!-- host -->` | [Runbook](<!-- link -->) | `<!-- status -->` |
+
+> **Note:** Replace placeholder rows with actual service entries.
+
+---
+
+## Directory Layout (per service)
+
+```
+services/<service-name>/
+├── README.md          ← Overview, ports, dependencies
+├── config/            ← Non-secret configuration files or excerpts
+└── runbook.md         ← Operational procedures (link or inline)
+```
+
+---
+
+## Standards
+
+- Document all exposed ports and upstream dependencies.
+- Reference the canonical runbook from `runbooks/` rather than duplicating procedures.
+- Mark services under active change with `⚠ IN FLUX` in the Status column.
