+#Statusbericht KW23 - TextureSync
+
+Sehr geehrter Herr Nikolaropoulos,
+
+hier der Statusbericht der vergangenen Woche TextureSync.
+
+#Vergangene Arbeitswoche
+
+* Robin Willmann erstelle die Netzwerk-Schnittstelle für den Client
+* Jannik Seiler und Hendrik Schutter erstellten die Logik des Clients
+* Lukas Fürderer erstellt einen Demo-Datensatz mit 1000 Texturen welche die Metadaten auf dem Bild darstellen
+* Robin Willmann erstellt das Wunschkriterium "Autoconnect" welches den Server automatisch findet
+
+#Nächste Arbeitswoche
+
+* Texturen ändern und Änderungen an den Server schicken
+* Alle Texturen beim Start anzeigen
+* Gefunden Texturen sofort anzeigen, nicht erst wenn alle gefunden sind
+* UI Style der MainView anpassen
+* Erste gefundene Textur initial ausgewählt
+* Beginn der Test des Clients und der Server-Client Kommunikation
+* Erstellen der Kurzanleitung
+
+#Aktuelle Informationen über das Projekt
+
+* Website mit aktuellem Projektplan: https://planner.mosad.xyz/TextureSync.html
+* Repository mit Code und Dokumenten: https://git.mosad.xyz/localhorst/TextureSync
+
+Sollten Sie Fragen haben, können Sie sich gern bei uns melden. 
+
+Mit freundlichen Grüßen
+
+Hendrik Schutter und Team TextureSync
