@ryanoasis The build failure above is unrelated.

Note: I also added a Visual Studio Code .devcontainer so I could use Remote WSL and Remote Containers to make these changes; other contributors should find this useful too as it captures the development environment requirements.

Also, I've no idea how FiraCode/config.json was originally derived, so I'm not sure if I need to update it...

Thanks for updating it 😃 . I need to pull it down and check it out but sounds pretty reasonable
