+# Prometheus
+
+Prompt evolution without reference data.
+
+## Quick Start
+
+```bash
+uv sync
+uv run prometheus optimize -i examples/sample_config.yaml -o result.yaml -v
+```
+
+## Architecture
+
+Clean hexagonal architecture with four layers:
+
+- **Domain** — entities, ports, scoring (zero external dependencies)
+- **Application** — use cases, bootstrap, evaluator, evolution loop
+- **Infrastructure** — DSPy signatures, modules, adapters, file I/O
+- **CLI** — Typer app with `optimize` command
+
+## Testing
+
+```bash
+uv run pytest
+uv run ruff check .
+uv run mypy src/
+```
