 If you are using this package with Amazon Lambda but are not also using `Amazon.Lambda.Serialization.Json`, be aware that one property requires custom serialization.
 
 This property is `Data` on the type `Amazon.Lambda.KinesisEvents.KinesisEvent+Record`. This is a `MemoryStream` object that should be populated by converting the JSON string from base64 to an array of bytes, then constructing a `MemoryStream` object from these bytes. Here is a code sample showing this deserialization logic.
-```

 string dataBase64 = GetJsonString();
 byte[] dataBytes = Convert.FromBase64String(dataBase64);
