+
+## 🌟 Overview
+
+**RelightFormer** revolutionizes image relighting by replacing traditional, computationally expensive inverse rendering with a feed-forward generative Transformer. By seamlessly injecting target lighting into spatial features and processing multiple views symmetrically, it delivers highly photorealistic results. Trained on the newly introduced, large-scale open-source **Laval-Objaverse Dataset (LOD)**, RelightFormer achieves state-of-the-art quality and remarkable generalization across diverse scenes.
+
+### ✨ Key Features
+- 🏹 **Feed-Forward Architecture**: No iterative optimization required, enabling rapid generation.
+- 🌟 **Multi-View Consistency**: Coherent and physically plausible relighting across all viewpoints.
+- ⚡ **Performant Inference**: Highly optimized and expeditious execution on modern GPUs.
+- 🎨 **Competitive Quality**: State-of-the-art, photorealistic relighting results.

+
+## 🚀 Quick Start
+
+You can easily load and run the model using the `diffsynth` library in our [GitHub Repository](https://github.com/vLAR-group/RelightFormer). 
+We provide two revisions: `main` (RelightFormer) and `post` (RelightFormer-Post, fine-tuned for enhanced quality).
+
+```python
+from diffsynth import RelightFormerPipeline
+
+# Use revision='main' for RelightFormer, or 'post' for RelightFormer-Post
+pipe = RelightFormerPipeline.from_pretrained(
+    "vLAR/RelightFormer", 
+    revision="main"
+)
+
+# Example inference (adjust inputs according to your specific pipeline API)
+# output = pipe(image=..., lighting=..., ...)
+```
+
+> 💡 **For full inference scripts, multi-GPU evaluation, and training code, please visit the [Official GitHub Repository](https://github.com/vLAR-group/RelightFormer).**

+
+## 🏋️ Training Details
+
+RelightFormer is fine-tuned from the **Wan 2.1** base model. The training pipeline consists of two stages:
+1. **Main Training**: Trained on the full LOD dataset to learn multi-view relighting priors.
+2. **Post-Training**: A secondary fine-tuning stage to further enhance photorealism and consistency.
+
+Detailed training configurations, hardware requirements (e.g., 4× H200 GPUs), and scripts are available in the [GitHub Repository](https://github.com/vLAR-group/RelightFormer).
