+# Boathouse Cafe
+
+A Symfony 8 web application for Boathouse Cafe.
+
+## Stack
+
+- **PHP 8.4** / **Symfony 8.0**
+- **FrankenPHP** (web server)
+- **Twig** (templating)
+- **Docker** (containerized dev & prod)
+
+## Requirements
+
+- Docker + Docker Compose
+- (Optional) PHP 8.4 + Symfony CLI for local development
+
+## Getting Started
+
+```bash
+# Build and start in dev mode (live reload)
+make start
+
+# App runs at http://localhost:8087
+```
+
+## Common Commands
+
+| Command | Description |
+|---|---|
+| `make start` | Start Docker containers in dev mode |
+| `make stop` | Stop all services |
+| `make restart` | Restart containers |
+| `make build` | Install deps and clear cache |
+| `make rebuild-docker` | Full rebuild from scratch |
+| `make test` | Run test suite |
+| `make lint-fix` | Fix code style |
+| `make logs` | Follow container logs |
+| `make shell` | Open shell in container |
+
+Run `make help` for the full list.
+
+## Development
+
+```bash
+# Install dependencies locally
+make install-deps
+
+# Start local Symfony dev server (no Docker)
+make start-local
+
+# Run tests
+make test
+
+# Check code style
+make lint-check
+```
+
+## Production
+
+```bash
+make start-prod
+```
+
+The production Docker image uses `docker-compose.yml` only (no dev overrides). The container serves on port 80; the host maps it to `8087`.
