+# Hub Guide — Asepharyana Hub Monorepo
+
+Guide for navigating and working with the Asepharyana Hub monorepo.
+
+## Submodule Workflow
+
+- Code changes go in the submodule repo, not here. The hub monorepo only tracks submodule pointers.
+- After pushing changes to a submodule repo, update the pointer here:
+  ```bash
+  cd apps/<name> && git checkout main && git pull
+  cd ../.. && git add apps/<name> && git commit -m "chore(deps): update <name> submodule"
+  ```
+- CI/CD auto-updates submodule pointers via `repository_dispatch`. Manual updates are fine for dev.
+
+### Typical Submodule State
+
+| State | Meaning |
+|-------|---------|
+| `(HEAD)` | Detached HEAD — submodule is at the committed pointer |
+| `(main)` | On the default branch — you've done `cd apps/name && git checkout main` |
+| Dirty | Uncommitted changes inside submodule |
+
+To reset a submodule to its committed pointer:
+```bash
+git submodule update --init --recursive apps/<name>
+```
+
+## Development Quickstart
+
+```bash
+make init-submodules     # After fresh clone — fetches all submodules
+make dev                 # Start Redis for local dev
+docker compose -f infra/compose/shared.yml up -d   # Full infra stack
+```
+
+## Local vs Production
+
+| Aspect | Local | Production (VPS) |
+|--------|-------|------------------|
+| DB | None (or local) | PostgreSQL on `imrnes` via Tailscale |
+| Redis | `make dev` | Container on `orangevps` |
+| Traefik | Not running | TLS-terminated on `orangevps` |
+| DNS | `localhost` | `*.asepharyana.my.id`, `*.asepharya.web.id` |
+
+## Debugging Tips
+
+### Docker compose validation
+```bash
+for f in infra/compose/*.yml; do docker compose -f "$f" config >/dev/null && echo "OK $f"; done
+```
+
+### YAML syntax check
+```bash
+python -c "import pathlib, yaml; [yaml.safe_load(open(p)) for p in pathlib.Path('infra').rglob('*.yml')]"
+```
+
+### Check submodule pointers
+```bash
+git submodule status
+  # Leading `-` = not initialized, `+` = different from committed hash, ` ` = matches
+```
+
+### Traefik route not working?
+1. Check `infra/traefik/dynamic/apps.yaml` — router rule + service definition present?
+2. Container labels in compose file include Traefik config?
+3. Container on `app-shared-net`?
+
+## Adding a New Service — Checklist
+
+1. [ ] Create separate repo for app code
+2. [ ] `git submodule add <url> apps/<name>`
+3. [ ] Create Dockerfile in `infra/docker/`
+4. [ ] Create compose file in `infra/compose/` (app + Dapr sidecar)
+5. [ ] Add Traefik router in `infra/traefik/dynamic/apps.yaml`
+6. [ ] Add build job in `.github/workflows/docker-build-push.yml`
+7. [ ] Verify: `docker compose -f infra/compose/<name>.yml config`
+
+See `docs/add-new-app.md` for full guide.
+
+## Monitoring
+
+- **Dashboard**: `/dashboard` on the hub site (auto-refresh 15s)
+- **Dashboard API**: `/api/dashboard` — JSON with containers, traces, metrics
+- **Prometheus**: Auto-discovers containers with `prometheus.io/scrape=true` label via Docker SD
+- **Jaeger**: Traces via OTLP — check for cross-service latency
+
+## Infrastructure Files Map
+
+| Path | Purpose |
+|------|---------|
+| `infra/compose/*.yml` | One Docker Compose file per service |
+| `infra/dapr/components/` | Dapr pub/sub, state store component configs |
+| `infra/docker/*.Dockerfile` | Build files per service |
+| `infra/traefik/dynamic/apps.yaml` | Traefik route definitions |
+| `infra/traefik/traefik.yml` | Traefik static config (entrypoints, providers) |
+| `.github/workflows/` | CI/CD pipelines |
+| `docs/` | ADRs, deployment guide, new-app guide |
+
+## Git Hook Scripts
+
+Located in `scripts/`:
+- `scripts/cleanup.sh` — prune old Docker images, clean temp files
+- `scripts/update-deps.sh` — bump dependencies across submodules
+- `scripts/setup-hooks.sh` — install local git hooks
