 ## Installation
 
-1. Bundle in dein Contao-Projekt legen (oder als VCS-Paket einbinden).
+Installation ueber Packagist:
-2. `composer install` oder `composer update acme/contao-dummy-copier`
-3. Cache leeren.
-4. Backend-Modul `Dummy Copier` unter `System` oeffnen.
 
-## Bedienung (aktueller Stand)
+```bash
+composer require webfarben/contao-dummy-copier
+```
 
-- Quellobjekte werden ueber Mehrfachauswahlfelder ausgewaehlt (Seiten, Module, Content, Verzeichnisse).
+Danach wie ueblich:
-- Seiten und Verzeichnisse werden in Baumdarstellung (Einrueckung nach Hierarchie) angezeigt.
-- Alle Mehrfachauswahlfelder haben Live-Filter sowie `Alle`/`Keine` Buttons.
-- Ziel-Elternseite wird per Auswahlfeld gesetzt.
 
-Bei kompatibler Contao-Umgebung nutzt das Modul native `pageTree`/`fileTree` Widgets fuer Seiten und Verzeichnisse.
+```bash
-Falls die Widget-Initialisierung versionsbedingt fehlschlaegt, wird automatisch auf die Select-Fallbacks gewechselt.
+php vendor/bin/contao-setup
-- Setze optional Zielverzeichnis, Zielartikel-ID und Praefix.
+php vendor/bin/console contao:migrate
-- Aktiviere Optionen nach Bedarf (`inkl. Content`, `Module kopieren`, `Verzeichnisse kopieren`, `Dry-Run`).
+```
 
-Hinweis: Das Modul akzeptiert weiterhin CSV-Werte als Fallback, falls du Felder per POST automatisiert befuellst.
+Das Backend-Modul `Dummy Copier` erscheint anschliessend unter `System`.
 
-## Wichtige Hinweise
+## Bedienung
 
-- Nach Verzeichnis-Kopien ggf. `contao:filesync` ausfuehren, damit DBAFS konsistent ist.
+- Quellobjekte werden ueber Mehrfachauswahlfelder ausgewaehlt.
-- Dieses Grundgeruest ist bewusst pragmatisch und kann erweitert werden um:
+- Seiten, Module, Newsarchive, Kalender und Verzeichnisse koennen separat kombiniert werden.
-  - PageTree/FileTree Picker statt CSV
+- Alle Mehrfachauswahlfelder besitzen Live-Filter sowie `Alle`/`Keine` Buttons.
-  - Feldspezifisches Mapping fuer News/Event/Archive-Felder in `tl_module`
+- Inhaltselemente von Seiten werden bei aktiver Option automatisch mitkopiert.
-  - Job-Queue via Messenger bei sehr grossen Kopierlaeufen
+- Ueber ein Praefix lassen sich Titel, Namen und Aliase der Kopien kenntlich machen.
+
+## Hinweise
+
+- Nach Dateikopien ggf. `php vendor/bin/console contao:filesync` ausfuehren, damit die DBAFS-Daten synchronisiert werden.
+- Das Bundle ist fuer pragmatische Redaktions- und Setup-Workflows gedacht. Projektspezifische Sonderfelder oder Referenzen koennen bei Bedarf erweitert werden.
+
+## Changelog
+
+- Siehe `CHANGELOG.md` fuer die dokumentierten Aenderungen ab `1.1.0`.
