+# Monlet Docs
+
+This directory contains operator-facing docs that do not fit in the root or component READMEs.
+
+## Start Here
+
+- [First deployment checklist](ops/deployment-checklist.md) - step-by-step production-ish stand-up checklist.
+- [Backup and restore](ops/backup-restore.md) - PostgreSQL backup, retention, and disaster recovery notes.
+- [Token rotation](ops/token-rotation.md) - UI token overlap and agent-key rotation.
+- [Deployment notes](ops/deployment.md) - deployment shape and production boundaries.
+
+## Conventions
+
+- Component setup lives in `agent/README.md`, `server/README.md`, `web/README.md`, and `deploy/README.md`.
+- API contracts live in `api/openapi.yaml`; `api/README.md` only describes contract rules.
+- Keep docs factual and current. Avoid placeholder docs when a real config or script already exists.
