+## ProdReadyApp (FastAPI + Postgres)
+
+A production-ready web application with authentication and task management built with FastAPI, SQLAlchemy, Alembic, and PostgreSQL. Includes Docker, CI, tests, and secure defaults.
+
+### Features
+- JWT auth (access + refresh), password hashing
+- Users + Tasks CRUD with ownership and admin controls
+- SQLAlchemy 2.0 + Alembic migrations
+- Health checks and Prometheus metrics
+- Rate limiting, CORS, secure headers
+- Gunicorn + Uvicorn workers
+- Docker Compose for local/dev/prod
+- GitHub Actions CI (lint + tests)
+
+### Quickstart (Docker)
+1. Copy env file:
+   ```bash
+   cp .env.example .env
+   ```
+2. Start services:
+   ```bash
+   docker compose -f infra/docker-compose.yml up --build
+   ```
+3. App available at `http://localhost:8000` (API docs at `/docs`).
+
+### Local (no Docker)
+```bash
+python -m venv .venv && source .venv/bin/activate
+pip install -r app/requirements.txt
+export $(grep -v '^#' .env.example | xargs)  # or create .env
+alembic -c app/alembic.ini upgrade head
+uvicorn src.main:create_app --factory --host 0.0.0.0 --port 8000 --app-dir app
+```
+
+### Useful Make targets
+```bash
+make setup    # install deps
+make run      # run dev server
+make test     # run tests
+make lint     # run linters
+make format   # format code
+make docker-up
+```
+
+### Migrations
+```bash
+alembic -c app/alembic.ini revision -m "message"
+alembic -c app/alembic.ini upgrade head
+```
+
+### Configuration
+Set environment variables (see `.env.example`). Defaults are safe for local dev. For production, always set `JWT_SECRET`, use strong DB credentials, and terminate TLS at a reverse proxy or load balancer.
+
+### Security Notes
+- Tokens are short-lived, refresh tokens persisted and revocable
+- Rate limits applied to auth routes
+- CORS is restricted via env
+- Non-root container user
+
+### License
+MIT
