+# UltraWan LoRA — ComfyUI Conversion (Unofficial)
+
+This repository contains **converted LoRA weights** from the official [**APRIL-AIGC/UltraWan**](https://huggingface.co/APRIL-AIGC/UltraWan) release.  
+The only modification made was converting the `.bin` / original format into `.safetensors` compatible with **ComfyUI**.  
+No training, fine-tuning, or architecture changes were performed.
+
+---
+
+## 📌 What This Is
+
+- ✅ Direct conversion of original UltraWan LoRA weights to **ComfyUI-compatible safetensors format**
+- ❌ Not trained, modified, or altered in any way beyond the format change
+- 🎯 For users who want to test **UltraWan LoRA** with ComfyUI’s Text-to-Video pipelines
