 Die`bot:on_msg_receive` Funktion fügt einige nützte Variablen zur ` msg` Tabelle hinzu. Diese sind:`msg.from.id_str`, `msg.to.id_str`, `msg.chat.id_str`, `msg.text_lower`, `msg.from.name`.
 
-Rückgabewerte für `plugin:action` sind optional, aber wenn eine Tabelle zurückgegeben wird, wird diese die neue `msg`,-Tabelle und `on_msg_receive` wird damit fortfahren.

 Interaktionen mit der Bot-API sind sehr einfach. Siehe [Bindings](#bindings) für Details.
 
 Einige Funktionen, die oft benötigt werden, sind in `utilites.lua` verfügbar.
