 - Automationen vorschlagen und direkt generieren
 - Lokal-first ohne Cloudpflicht
 - Erweiterbar, testbar, dokumentiert
+
+## Lokaler Quickstart
+
+Voraussetzung ist Python 3.11 oder neuer.
+
+```bash
+python -m venv .venv
+. .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+cp .env.example .env
+```
+
+In `.env` müssen für echte Home-Assistant-Daten diese Werte gesetzt werden:
+
+```bash
+SILLYHOME_HA_URL=http://homeassistant.local:8123
+SILLYHOME_HA_TOKEN=<long-lived-access-token>
+```
+
+Alternativ werden aus Kompatibilitätsgründen auch `HA_URL` und `HA_TOKEN` gelesen.
+Tokens bleiben lokal und dürfen nicht committed, geloggt oder in Issues kopiert werden.
+
+API starten:
+
+```bash
+uvicorn app.main:app --reload
+```
+
+Nützliche Checks:
+
+```bash
+curl http://127.0.0.1:8000/health
+curl http://127.0.0.1:8000/v1/entities
+```
+
+Die interaktive API-Dokumentation liegt unter `http://127.0.0.1:8000/docs`.
+
+## Qualität
+
+Vor jedem Pull Request lokal laufen lassen:
+
+```bash
+pytest -q
+ruff check .
+mypy app tests
+```
+
+Der Gitea-Actions-Workflow in `.gitea/workflows/quality.yml` führt dieselben Checks für
+Pushes und Pull Requests aus.
