+By default the Azure Blob Storage output binding will auto generate a UUID as blob filename and not assign any system or custom metadata to it. It is configurable in the Metadata property of the message (all optional).
+
+Applications publishing to an Azure Blob Storage output binding should send a message with the following contract:
+```json
+{
+    "data": {
+        "message": "Hi"
+    },
+    "metadata": {
+        "blobName"           : "filename.txt",
