 ### Override (Optional)
 
 **Generation Parameters:**
@@ -124,7 +134,13 @@ For custom benchmarking, connect these hidden inputs:
 - `gpu_device_override` - Override GPU device name
 - `generation_time_override` - Manual generation time (or from Timer node)
 
-All overrides use `forceInput: True` (hidden from UI, connection-only).
+All generation-parameter sockets are optional. They use `forceInput: True` so
+ComfyUI shows them as connection inputs, but they are not required for normal
+saving. A good default setup is:
+
+- `VAEDecode.IMAGE` -> `MetaHub Save Image.images`
+- optional `MetaHub Timer.elapsed_time` -> `generation_time_override`
+- optional manual overrides only when the console says a field was not detected
 
 ### Filename Pattern
 Use `filename_pattern` to customize names (default `ComfyUI_%counter%`). Invalid filename characters are sanitized and missing values become `unknown`. `filename_prefix` is deprecated but still supported.
