@@ -12,13 +12,25 @@ Web-App zur Planung und Verwaltung von Morning-Meeting-Moderatoren.
 - **Verlauf** – Vergangene Monatspläne einsehen und wiederherstellen
 - **Persistenz** – Automatische Speicherung im Browser (localStorage)
 
+## Tech-Stack
+
+- **Vanilla JavaScript (ES-Module)** – kein Framework, **kein Build-Schritt**
+- **Persistenz:** Browser-`localStorage` (kein Backend, keine Datenbank)
+- **Excel-Im-/Export:** [SheetJS](https://sheetjs.com/) (per CDN, mit SRI eingebunden)
+- **Statisches Serving:** [`serve`](https://www.npmjs.com/package/serve) (Dev)
+- **Tests:** Node-Assertions (`node:assert`), ohne externe Abhängigkeiten
+
+Voraussetzung: ein moderner Browser mit ES-Modul-Unterstützung.
+
 ## Starten
 
 ```bash
 npm start
 ```
 
-Die App läuft auf **http://localhost:3001**.
+Startet einen statischen Server. Der genutzte Port wird beim Start ausgegeben
+(Standard 3001; weicht automatisch aus, falls belegt). Öffne anschließend die
+angezeigte URL im Browser.
