+  config_version: 2
+
+config:
+  # enable/disable audit logging
+  enabled: true
+
+  ...

+
+  compliance:
+    # enable/disable compliance
+    enabled: true
+
+    # Log updates to internal security changes
+    internal_config: true
+
+    # Log only metadata of the document for write events
+    write_metadata_only: false
+
+    # Log only diffs for document updates
