 ## Git-Workflow
 
+### Pre-Commit Hooks aktivieren
+
+Die Pre-Commit Hooks (Husky + lint-staged) werden automatisch beim Installieren der Abhängigkeiten eingerichtet:
+
+```bash
+npm install
+```
+
+Der `prepare`-Script in `package.json` (`"prepare": "husky"`) sorgt dafür, dass Husky die Git Hooks im `.husky/`-Verzeichnis registriert. Nach `npm install` sind die Hooks aktiv – kein manueller Schritt nötig.
+
+> **Falls Hooks nicht laufen:** Prüfe ob `.husky/pre-commit` ausführbar ist (`chmod +x .husky/pre-commit`) und ob `core.hooksPath` nicht überschrieben wurde (`git config core.hooksPath`).
+
+### Was wird beim Commit geprüft?
+
 Beim Committen führt **Husky** automatisch den Pre-Commit Hook (`.husky/pre-commit`) aus, der **lint-staged** startet.
