 # UmlautAdaptarr
 
-## Testversion kommt in wenigen Tagen
+## English description coming soon
 
-### Kleine Preview
+## Erste Testversion
+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 und Lidarr schon Auswirkungen (abgesehen vom Caching).
+
+Momentan ist docker dafür nötig, wer kein Docker nutzt muss sich noch etwas gedulden. 
+
+[Link zum Docker Image](https://hub.docker.com/r/pcjones/umlautadaptarr)
+
+Zusätzlich müsst ihr in Sonarr oder Prowlarr einen neuen Indexer hinzufügen (für jeden Indexer, bei dem UmlautAdapdarr greifen soll).
+
+Am Beispiel von sceneNZBs:
+
+![grafik](https://github.com/PCJones/UmlautAdaptarr/assets/377223/07c7ca45-e0e5-4a82-af63-365bb23c55c9)
+
+Also alles wie immer, nur dass ihr als API-URL nicht direkt z.B. `https://scenenzbs.com` eingebt, sondern 
+`http://localhost:5005/_/scenenzbs.com`
+
+Den API-Key müsst ihr natürlich auch ganz normal setzen.
+
+## Was macht UmlautAdaptarr überhaupt?
+UmlautAdaptarr löst mehrere Probleme:
+- 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)
+- 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.
+
+# 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, das die Arrs sie einwandfrei erkennen.
+Einige Beispiele findet ihr unter Features.
+

+
+
+**Vorher:** Die deutsche Produktion `Alone - Überlebe die Wildnis` hat auf [TheTVDB](https://thetvdb.com/series/alone-uberlebe-die-wildnis) den Englischen Namen `Alone Germany`.
+
+Sonarr erwartet immer den Englischen Namen, der hier natürlich nicht gegeben ist.

+
+**Jetzt:** UmlautAdaptarr hat die Releases in `Alone Germany` umbenannt und Sonarr hat keine Probleme mehr
+![grafik](https://github.com/PCJones/UmlautAdaptarr/assets/377223/57539ffc-b8a6-4255-a7f8-03079c10b1e8)
+
+**Vorher:** Hier wird der komplette deutsche Titel im Release angegeben (also mit `- Das Lied von Eis und Feuer`) - glücklicherweise stellt uns [TheTVDB](https://thetvdb.com/series/game-of-thrones) aber diesen längeren Titel als Alias zur Verfügung - nur nutzt Sonarr diese Informationen (bisher) einfach nicht.
+![grafik](https://github.com/PCJones/UmlautAdaptarr/assets/377223/8f3297bd-ebe4-42de-b4e6-952882c8b902)
+
+**Jetzt:** UmlautAdapatarr erkennt alle auf TheTVDB angegebenen Aliase und benennt das Release in den Englischen Titel um
