### Basic Workflow
1. Connect your image source to the `Image` input
2. Set your desired minimum and maximum resolution constraints
3. Connect the `Image` output to your preferred resize node (e.g., Image Resize)
4. Use the `Constrained Width` and `Constrained Height` outputs to set the dimensions in your resize node
3. Set the "Multiple Of" value based on your model requirements (e.g., 8 for SDXL)
4. Connect the `Image` output to your preferred resize node (e.g., Image Resize)
5. Use the `Constrained Width` and `Constrained Height` outputs to set the dimensions in your resize node
