 SGLang Diffusion supports AMD Instinct GPUs through ROCm. On AMD platforms, we use the Triton attention backend and leverage AITER kernels for optimized layernorm and other operations. See the [ROCm installation guide](https://github.com/sgl-project/sglang/tree/main/python/sglang/multimodal_gen/docs/install_rocm.md) for setup instructions.
 
+### Moore Threads/MUSA Support
+
+SGLang Diffusion supports Moore Threads GPUs (MTGPU) through the MUSA software stack. On MUSA platforms, we use the Torch SDPA backend for attention. See the [MUSA installation guide](https://github.com/sgl-project/sglang/tree/main/python/sglang/multimodal_gen/docs/install_musa.md) for setup instructions.

 ## Getting Started
 
 ```bash
 uv pip install 'sglang[diffusion]' --prerelease=allow
 ```
 
-For more installation methods (e.g. pypi, uv, docker), check [install.md](https://github.com/sgl-project/sglang/tree/main/python/sglang/multimodal_gen/docs/install.md). ROCm/AMD users should follow the [ROCm quickstart](https://github.com/sgl-project/sglang/tree/main/python/sglang/multimodal_gen/docs/install_rocm.md) that includes the additional kernel builds and attention backend settings we validated on MI300X.
