+### Cuda installation
+
+To be able to install CUDA, you first need a compatible NVIDIA GPU.  Once you have the GPU and display driver installed, you can follow the [official instructions](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html) or [this blog](https://www.pugetsystems.com/labs/hpc/How-To-Install-CUDA-10-1-on-Ubuntu-19-04-1405/) to setup CUDA
