-# 🎵 WAV zu MP3 Konverter
+# fcco Converter V2
 
-Ein einfaches, benutzerfreundliches Python-Tool mit grafischer Oberfläche (Tkinter), das WAV-Dateien in MP3-Dateien konvertiert. Es unterstützt automatische Metadaten-Erstellung (Künstler, Album, Titel, Tracknummer) und fügt sogar ein Cover-Bild ein. Alle Dateien werden automatisch alphabetisch sortiert.
+WAV-zu-MP3-Konverter mit grafischer Benutzeroberfläche. Unterstützt automatische Metadaten-Erstellung (Künstler, Album, Titel, Tracknummer), Cover-Bilder und alphabetische Sortierung. Läuft auf **Windows** und **macOS**.

-## ✅ Features
+## Features
 
-- 📂 Mehrere WAV-Dateien auswählen
-- 📝 Standard-Metadaten definieren (Künstler, Album, Cover)
-- 🧠 Vorschau & Bearbeitung der Metadaten vor der Konvertierung
-- 🔄 Automatische Sortierung nach Dateinamen
-- 🖼️ Cover-Bild einfügen
-- 💾 Einstellungen werden gespeichert (Metadaten & letzter Export-Ordner)
-- 📊 Fortschrittsbalken während der Konvertierung
+- Mehrere WAV-Dateien oder ganze Ordner (mit Unterordnern) auswählen
+- Metadaten definieren und bearbeiten (Künstler, Album, Jahr, Cover)
+- Automatische Sortierung nach Dateinamen
+- Cover-Bild einfügen (JPG/PNG)
+- Einstellungen werden dauerhaft gespeichert
+- Fortschrittsanzeige pro Datei und gesamt
+- Automatisches Update direkt aus der App
+- Moderne, dunkle Benutzeroberfläche (CustomTkinter)
 
 ---
 
-## 🛠️ Setup
+## Installation (Endnutzer)
 
-# Automatisches Setup starten
-Windows-Nutzer können einfach ````setup.bat````` ausführen – es installiert:
--	Python (falls nicht vorhanden)
--	Virtuelle Umgebung
--	Alle benötigten Python-Pakete (pydub, mutagen)
--	FFmpeg (wird automatisch heruntergeladen & eingebunden)
+Lade die neueste Version von der [Releases-Seite](https://git.joelunger.de/public/fcco-Converter/releases) herunter:
 
-# Alternativ: Manuell installieren
-1. Stelle sicher, dass Python 3.11 oder neuer installiert ist.
-2. Virtuelle Umgebung erstellen und aktivieren:
-````python -m venv .venv
-.venv\Scripts\activate````
+- **Windows**: `fcco-Converter-windows.zip` entpacken und `fcco-Converter.exe` starten.
+- **macOS**: `fcco-Converter-macos.zip` entpacken und `fcco-Converter` starten.
 
-3. Abhängigkeiten installieren:
-`````pip install pydub mutagen````
+FFmpeg wird automatisch beim ersten Start heruntergeladen. Keine weitere Installation nötig.
 
-4. FFmpeg herunterladen und den bin-Ordner zur PATH-Umgebungsvariable hinzufügen.
+---
 
-# 🚀 Anwendung starten
-1. main.py ausführen:
-````.venv\Scripts\python.exe main.py````
+## Updates
 
-2. WAV-Dateien auswählen und konvertieren.
+In der App auf **"Update prüfen"** klicken. Wenn eine neue Version verfügbar ist, wird sie direkt heruntergeladen und installiert. Danach muss die App einmal neu gestartet werden.
