+
+## 🌿 Introduction
+
+We present TokenFlow, a unified image tokenizer that bridges the long-standing gap between multimodal understanding and generation. 
+TokenFlow introduce an innovative dual-codebook architecture that decouples semantic and pixel-level feature learning while maintaining their alignment through a shared mapping mechanism. 
+
+TokenFlow excels in both multimodal understanding and image generation. For multimodal understanding, we surpass the flagship models such as LLaVA-1.5 and EMU3 by a large margin. For text-to-image generation, we also achieve comparable performance to SDXL in 256×256 resolution.
+
+
+## ⚙️ Getting Started
+This repo contains the model for text-to-image in TokenFlow.
+See [GETTING_STARTED.md](https://github.com/ByteFlow-AI/TokenFlow/blob/main/GETTING_STARTED.md) for detailed instructions of ***training*** and ***evaluation*** of TokenFlow multimodal understanding.
