+
+## Optimization Guidelines
+
+### Recommended Combinations
+
+#### Speed Optimized
+```
+Sampler: euler or dpm_fast
+Scheduler: normal or simple
+Steps: 15-25
+CFG: 6.0-8.0
+```
+
+#### Quality Optimized  
+```
+Sampler: dpmpp_2m_sde or dpmpp_3m_sde
+Scheduler: karras
+Steps: 25-35
+CFG: 7.0-9.0
+```
+
+#### Balanced
+```
+Sampler: dpmpp_2m or heun
+Scheduler: karras or normal
+Steps: 20-30
+CFG: 7.0-8.5
+```
+
+### Steps Recommendations
+
+| Sampler Type | Min Steps | Optimal | Max Steps |
+|--------------|-----------|---------|-----------|
+| Fast (euler, dpm_fast) | 10 | 20 | 30 |
+| Standard (heun, dpm_2) | 15 | 25 | 40 |
+| Advanced (dpmpp_*) | 20 | 30 | 50 |
+| Adaptive | 10 | 25 | 100 |
+
+### CFG Scale Guidelines
+
+| Content Type | CFG Range | Recommended |
+|--------------|-----------|-------------|
+| Photorealistic | 5.0-8.0 | 7.0 |
+| Artistic/Stylized | 7.0-12.0 | 9.0 |
+| Abstract/Creative | 8.0-15.0 | 11.0 |
+| Text/Details | 10.0-20.0 | 13.0 |
+
+## Usage Examples
+
+### Basic Configuration
+```
+sampler_name: euler
+scheduler: normal  
+steps: 20
+cfg: 7.0
+```
+
+### High Quality Setup
+```
+sampler_name: dpmpp_2m_sde
+scheduler: karras
+steps: 30
+cfg: 8.0
+```
+
+### Speed Priority
+```
+sampler_name: dpm_fast
+scheduler: simple
+steps: 15
+cfg: 6.5
+```
+
+## Advanced Features
+
+### Compatibility Analysis
+The node provides real-time analysis of parameter compatibility:
+- Scheduler compatibility with selected sampler
+- Steps optimization for sampler type  
+- CFG scale recommendations
+- Performance impact assessment
+
+### Error Handling
+- Invalid samplers default to 'euler'
+- Invalid schedulers default to 'normal'
+- Out-of-range steps clamped to valid range
+- Invalid CFG values sanitized to safe defaults
+
+### Performance Tips
+1. **Use Karras scheduler** for most samplers (better quality)
+2. **Start with 20-30 steps** for most use cases
+3. **Keep CFG 6.0-9.0** for realistic images
+4. **Try dpmpp_2m** for best speed/quality balance
+5. **Use euler** for fastest generation
+
+## Troubleshooting
+
+### Common Issues
+- **Slow generation**: Try euler or dpm_fast samplers
+- **Poor quality**: Increase steps or try dpmpp_2m_sde
+- **Overcooked images**: Lower CFG scale
+- **Underdetailed**: Increase CFG or steps
+- **Artifacts**: Try karras scheduler or different sampler
+
+### Performance Optimization
+- **GPU Memory**: Lower steps if running out of VRAM
+- **Speed**: Use euler + normal + 15-20 steps
+- **Quality**: Use dpmpp_2m_sde + karras + 25-30 steps
+- **Compatibility**: Stick to euler/heun for broad model support
+
+## Integration
+
+The Sampler Combo node outputs are compatible with all standard ComfyUI sampling nodes:
+- KSampler
+- KSamplerAdvanced  
+- Custom sampling workflows
+- Upscaling pipelines
+- Img2img workflows
+
+Connect the outputs directly to your sampling node inputs for streamlined configuration.
