+### CUDA Architectures
+
+Different NVIDIA GPUs have different CUDA architecture: [CUDA GPU Compute Capability](https://developer.nvidia.com/cuda-gpus)
+
+To build for multiple GPU architectures (matching the GitHub CI releases), use `-DCMAKE_CUDA_ARCHITECTURES=90;89;86;80;75`:
+
+```shell
+mkdir build && cd build
+cmake .. -DSD_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=90;89;86;80;75
+cmake --build . --config Release
+```

 ## Build with HipBLAS
 
 This provides GPU acceleration using AMD GPU. Make sure to have the ROCm toolkit installed.
