# Project Documentation Index: Starter Template

Technical index for developers and AI agents. Use this as the entry point to all `docs/` files.

---

## Documentation Languages
- Technical docs: English (`docs/` and subfolders).
- Repository summary: `README.md` (Russian).  
  New documents should be added in English unless noted.

---

## Documentation Structure (root: `docs/`)

### 1) General Project Docs
- `docs/project-overview.md` — goals, target users, value proposition, key flows (data ingestion, processing, human approvals, reporting, billing), non-functional requirements.
- `docs/phases-plan.md` — Phase 0–4 plan with tasks across product, frontend, backend, infra, data/LLM.
- `docs/content-structure.md` — high-level UI/content structure and page sections.

### 2) Frontend (`/docs/frontend`)
- `docs/frontend/overview.md` — frontend scope, key user journeys (onboarding, data connection, approvals, reports).
- `docs/frontend/architecture.md` — recommended stack and patterns (feature-first structure, data fetching, styling).
- `docs/frontend/FRONTEND_ARCHITECTURE_PLAN.md` — planning notes for frontend architecture decisions.
- `docs/frontend/ui-ux-guidelines.md` — UX/UI guidance for data review and approval flows.
- `docs/frontend/seo-performance.md` — performance and SEO recommendations.

### 3) Backend (`/docs/backend`)
- `docs/backend/overview.md` — backend scope: ingestion, processing (rules + embeddings + LLM), approvals, reporting, billing.
- `docs/backend/architecture.md` — stack and module boundaries (provider-agnostic recommendations).
- `docs/backend/api-design.md` — API resources and conventions (entities, rules, approvals, reports, billing, events).
- `docs/backend/security.md` — authN/Z, secret handling, webhook verification, audit/event logging.
- `docs/backend/payment-flow.md` — payment integration (provider-agnostic template; single source of truth for payment flows and webhooks).

## How to Use This Index
- **New to the project:** read `project-overview.md` and `phases-plan.md` first.
- **Designing features:** use frontend/backend architecture docs plus API/security/payment flow specs.
- **Expanding docs:** add new English `*.md` files under `docs/` and update this index with links.
