 ### libdave Log Sink
 
 By default, `libdave` writes its logs to standard output, you can override that by specifying a custom log sink:
-```cs
-Discord.LibDave.Dave.SetLogSink(MyLogSink);
-
-void MyLogSink(
-    Discord.LibDave.LoggingSeverity severity, 
-    string filePath,
-    int lineNumber,
-    string message
-)
-{
-    // do what you want with the logs
-    Console.WriteLine($"[{severity} | LIBDAVE @ {file}#{line}]: {message}");
-}
