+Hallo zusammen! Dies ist eine kleine Info über das Projekt.
+Ich habe mir dieses Projekt auf der selben Ebenen wie Data gedacht.
+
+Data: ist ein Projekt, was speziell für die Datenbank Logik dient.
+ApiFacade: soll im Gegenzug ein Projekt darstellen, was rein für die API Kommunikation gedacht ist.
+
+Aktuell beinhaltet es die basischen Klassen HttpClientFacade und JsonHttpClientFacade.
+WebClientFacade wird nicht benutzt.
+
+HttpClientFacade stellt eine Facade für einen Api Endpunkt bereit, welche mit GET angesporchen werden.
+Parameter werden dabei in der Query übergeben, der Body bleibt unberüht!
+
+JsonClientFacade stellt eine Facade für Api Endpunkte bereit, welche mit POST angesprochen werden.
+
+Es wäre hier definitiv eine Überlegung wert, ob man die konkreten Implentiereungen nicht doch auch hier vornimmt, 
+sauber getrennt durch Ordner.
+Das wäre auch nicht so schlecht, weil Data als Idee auch abgeschlossen für die DB Interaktionen dient. 
+Ich behalte das mal im Hinterkopf, es würde wenn den gesamten Ordner Server/Features/AICore/Facade betreffen.
+
+Danke fürs lesen :)
