+## 🎓 Training
+
+> 💡 Training code is coming soon. We will release the complete training pipeline in the future.
+
+HunyuanVideo-1.5 is trained using the **Muon optimizer**, which accelerates convergence and improves training stability. The Muon optimizer combines momentum-based updates with Newton-Schulz orthogonalization for efficient optimization of large-scale video generation models.
+
+### Creating a Muon Optimizer
+
+Here's how to create a Muon optimizer for your model:
+
+```python
+from hyvideo.optim.muon import get_muon_optimizer
+
+# Create Muon optimizer for your model
+optimizer = get_muon_optimizer(
+    model=your_model,
+    lr=lr,                      # Learning rate
+    weight_decay=weight_decay,  # Weight decay
+    momentum=momentum,          # Momentum coefficient
+    adamw_betas=adamw_betas,   # AdamW betas for 1D parameters
+    adamw_eps=adamw_eps        # AdamW epsilon
+)
+```
+
+> 📝 **To be continued**: More training details and the complete training pipeline will be released soon. Stay tuned!
