    - Adjust the number of workers based on your available GPUs
    - Update CUDA device numbers if needed
    - Set appropriate ports (ensure they're not in use)
+   - Add custom launch arguments in `extra_args` for master and workers
 
 3. Run the launcher script from the ComfyUI root directory:
    ```bash
    launch_distributed.bat
    ```
-   This will automatically start ComfyUI instances for each GPU
 
 4. Open the master instance (usually http://localhost:8188)
 
 5. Add the "Multi-GPU Collector" node to your workflow
 
 6. Use the GPU control panel in the sidebar to:
-   - Select which GPUs to use
-   - Choose between parallel or staggered execution
-   - Clear VRAM when needed
+   - View GPU status and worker information
+   - Monitor active instances

 ## Performance Considerations
 
-- **Parallel Mode**: Best for workflows with consistent VRAM usage
-- **Staggered Mode**: Ideal for memory-intensive workflows or when GPUs have different VRAM capacities
+- **Parallel Execution**: All enabled GPUs process simultaneously for maximum throughput
 - **Batch Size**: Total generation = batch_size × number_of_active_GPUs
+- **Smart Launching**: The launcher only starts instances that aren't already running
+- **Memory Management**: Use appropriate `extra_args` in configuration for memory optimization
 
 ## Troubleshooting
 
 - **Workers not connecting**: Ensure CORS headers are enabled (`--enable-cors-header`)
-- **VRAM errors**: Use staggered mode with appropriate delays
-- **Timeout errors**: Increase `job_timeout` in configuration
+- **VRAM errors**: Add memory management flags in `extra_args` (e.g., `--highvram`, `--disable-smart-memory`)
 - **Port conflicts**: Ensure each instance uses a unique port
+- **Partial startup**: The launcher will automatically start only missing instances without affecting running ones
