1. Install the NPM dependency under your user account

    npm install xeokit/xeokit-gltf-to-xkt -g

2. install your distribution's version of .NET core:

   Ubuntu:
   - Don't use snap for installing the .NET Runtime 3.1. It's broken. Use the DPKG packages:
   - Follow the instructions for Ubuntu installation https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

   Other OSes, check out and install runtime 3.1:
