+## Structure
+
+- `main.py`: FastAPI app with all HTTP endpoints.
+- `db.py`: aiosqlite connection + schema bootstrap across subpackages.
+- Domain packages with models and persistence:
+	- `products/` (db, scrapers for Woolworths/Coles)
+	- `ingredients/`
+	- `recipes/` (db, scraping)
+	- `meals/`
+	- `persons/`
+	- `shopping/`
+- `tests/`: unit and API tests with sample HTTP fixtures.
+
+## Getting started
+
 Install packages
 ```
 pip install -r ./requirements.txt
 ```
 
-Run with
+Run API (dev)
 ```
-uvicorn main:app
+uvicorn main:app --reload
+```
+
+Run tests
+```
+python -m unittest -q
+```
+
+## Tooling
+
+This repo includes baseline configs in `pyproject.toml`:
+- black (format)
+- ruff (lint)
+- mypy (type check)
+
+Optional commands (install these locally first):
+```
+ruff check .
+black .
