Generate a production-ready, 2000+ word README.md for software features in Nx/Turborepo monorepos, detailing architecture, backend (NestJS), frontend (React/Next.js), database schemas, integrations, setup, usage, and API docs from directory structures.

Prompt

You are an expert software architect, full-stack developer, and technical documentation specialist with deep knowledge of NestJS (backend), React/Next.js (frontend), TypeScript, CASL (abilities), TanStack Query, Zustand, WebSockets, and monorepo setups using Nx or Turborepo.

Your task is to generate an **extensive, professional README.md file** for the new feature named **[FEATURE_NAME]** (e.g., 'Mapa Completo - Feature Security'). Use the provided directory structure **[DIRECTORY_STRUCTURE]** as the primary source of truth. Infer functionality, relationships, data flows, and database schemas from file names, paths, and descriptions. Explain **everything the feature does step-by-step**, including:
- High-level overview and business value.
- Architecture diagram (use Mermaid or ASCII art).
- Backend: Controllers/endpoints (list all with methods/paths), services (logic flows), repositories (DB models/inferred schemas), validators, middleware, WebSockets, auth/permissions (CASL integration).
- Database: Inferred schemas, migrations, relationships (e.g., permissions, cargos, funcionarios).
- Frontend: Components (hierarchy/UI flows), hooks (data fetching/caching), services (API/WebSocket calls), stores (state management), pages/routing.
- Shared: Types, constants, registries.
- Integration: How backend/frontend connect (e.g., Axios, ability context, middleware).
- Setup/Installation steps.
- Usage guide: Step-by-step workflows (e.g., CRUD permissions, real-time online users).
- API documentation (table of endpoints).
- Testing strategy.
- Future improvements.

Make it **production-ready, markdown-formatted, 2000+ words**, with emojis, badges, tables, code blocks, and links to files. Use **[ADDITIONAL_CONTEXT]** for extra details (e.g., DB tech like PostgreSQL, specific behaviors).

Output **ONLY the complete README.md content** in a single markdown code block, starting with '# [FEATURE_NAME]'.

**Directory Structure:**
[DIRECTORY_STRUCTURE]

**Additional Context:**
[ADDITIONAL_CONTEXT]

How to Use

Replace [FEATURE_NAME] with the feature name (e.g., 'User Authentication'), paste the actual directory tree into [DIRECTORY_STRUCTURE] (use tools like tree command), add any extra details like DB tech or behaviors in [ADDITIONAL_CONTEXT], then feed the full prompt to an AI like Claude or GPT-4 for instant README generation. Review and tweak the output for your repo.
