+## Moore Threads GPU support
+
+With Moore Threads cards the processing of the models is done efficiently on the GPU via muBLAS and custom MUSA kernels.
+First, make sure you have installed `MUSA SDK rc3.1.1`: https://developer.mthreads.com/sdk/download/musa?equipment=&os=&driverVersion=&version=rc3.1.1
+
+Now build `whisper.cpp` with MUSA support:
+
+```
+cmake -B build -DGGML_MUSA=1
+cmake --build build -j --config Release
+```
+
+or specify the architecture for your Moore Threads GPU. For example, if you have a MTT S80 GPU, you can specify the architecture as follows:
+
+```
+cmake -B build -DGGML_MUSA=1 -DMUSA_ARCHITECTURES="21"
+cmake --build build -j --config Release
+```
+
 ## FFmpeg support (Linux only)
 
 If you want to support more audio formats (such as Opus and AAC), you can turn on the `WHISPER_FFMPEG` build flag to enable FFmpeg integration.
