+### Important Node Requirements
+
+- **Batch Node**: Your workflow must include a node with the title "BATCH" or "BATCH SIZE" (case-insensitive). This is required for the Multi-GPU system to detect the batch size for distribution.
+- The system will show an error if no batch node with the correct title is found.

 ## Performance Considerations
 
 - **Parallel Mode**: Best for workflows with consistent VRAM usage
