# Documentation Updater

Keep documentation aligned with this frontend monorepo. Follow `.cursor/rules/documentation.mdc` and `.cursor/rules/user-docs.mdc`.

## Documentation split

| Kind | Location | Audience |
| --- | --- | --- |
| User | `apps/docs-dev/` (VitePress) | Customers / operators — features and usage (web + mobile) |
| Technical | sibling `trackgo-be/docs/` + `mkdocs.yml` | Developers — stack, architecture, how to run |

Going forward, **do not** add developer architecture, package API, desktop IPC, or setup/stack pages under `apps/docs-dev`. Prefer `src/user/web/` and `src/user/mobile/`. Existing legacy architecture pages stay until a later migration — do not expand them.

## Source of truth

1. Code in `apps/web`, `apps/landing`, and sibling `trackgo_mobile` (menus, modules, routes)
2. Root and package `package.json` scripts
3. `apps/web/.env.example` (`VITE_*` only; public to the client)
4. `apps/showcase` — component/API shape (prefer over stale docs)
5. Root `README.md` for local run commands

If a product brief disagrees with code, follow the code or label **Coming soon**. No emoji. Diagrams: PlantUML, not Mermaid. Icons: `lucide-vue-next`.

Do not create `docs/CONTRIB.md` or `docs/CODEMAPS` unless they already exist. Do not invent NestJS/Drizzle maps inside this frontend repo — put those in trackgo-be MkDocs.

## Workflow

1. For **user** doc changes: update VitePress under `apps/docs-dev` (prefer `src/user/…`); register nav in `src/.vitepress/config.mts`
2. For **technical** FE/landing/mobile docs: edit sibling `trackgo-be/docs/` and `mkdocs.yml` (see trackgo-be `technical-docs.mdc`)
3. Keep root README run commands accurate (`pnpm install`, `pnpm dev:web`, `pnpm dev:showcase`, `pnpm dev:docs-dev`)
4. List user docs not touched in 90+ days for manual review
5. Show a diff summary

## Quality

- Every path mentioned must exist
- Commands must match `package.json`
- No NestJS, Drizzle, or PostgreSQL as this app's stack in user docs
- No emoji; PlantUML for diagrams; Lucide via `lucide-vue-next` when icons are needed
