 # UmlautAdaptarr
 
-## English description coming soon
+ A tool to work around Sonarr, Radarr, Lidarr and Readarrs problems with foreign languages.
+
+## Detailed English description coming soon
 
 ## Beschreibung
-Wer möchte kann den UmlautAdaptarr jetzt gerne testen! Über Feedback würde ich mich sehr freuen!
-
-Es sollte mit allen *arrs funktionieren, hat aber nur bei Sonarr, Readarr und Lidarr schon Auswirkungen (abgesehen vom Caching).
 
 UmlautAdaptarr löst mehrere Probleme:
-- Releases mit Umlauten werden grundsätzlich nicht korrekt von den *Arrs importiert
+- Releases mit Umlauten werden grundsätzlich nicht korrekt von den *arrs importiert
-- Releases mit Umlauten werden oft nicht korrekt gefunden (*Arrs suchen nach "o" statt "ö" & es fehlt häufig die korrekte Zuordnung zur Serie/zum Film beim Indexer)
+- Releases mit Umlauten werden oft nicht korrekt gefunden (*arrs suchen nach "o" statt "ö" & es fehlt häufig die korrekte Zuordnung zur Serie/zum Film beim Indexer)
 - Sonarr & Radarr erwarten immer den englischen Titel von https://thetvdb.com/ bzw. https://www.themoviedb.org/. Das führt bei deutschen Produktionen oder deutschen Übersetzungen oft zu Problemen - falls die *arrs schon mal etwas mit der Meldung `Found matching series/movie via grab history, but release was matched to series by ID. Automatic import is not possible/` nicht importiert haben, dann war das der Grund.
+- Releases mit schlechtem Naming (z.B. von der Group TvR die kein "GERMAN" in den Releasename tun) werden korrigiert, so dass Sonarr&Radarr diese korrekt erkennen (optional)
 - Zusätzlich werden einige andere Fehler behoben, die häufig dazu führen, dass Titel nicht erfolgreich gefunden, geladen oder importiert werden.
 
 ## Wie macht UmlautAdaptarr das?
 UmlautAdaptarr tut so, als wäre es ein Indexer. In Wahrheit schaltet sich UmlautAdaptarr aber nur zwischen die *arrs und den echten Indexer und kann somit die Suchen sowie die Ergebnisse abfangen und bearbeiten.
 Am Ende werden die gefundenen Releases immer so umbenannt, dass die Arrs sie einwandfrei erkennen.
-Einige Beispiele finden sich [weiter unten](https://github.com/PCJones/UmlautAdaptarr/edit/develop/README.md#beispiel-funktionalit%C3%A4t).
