@mrmhodak @swasson488 please consider this MR for updating NVIDIA's documentation.

Please provide:

1. Description of changes; There is a large block of instructions removed and replaced by a different one.
2. Why is this needed? The README had been reviewed, we should not been adding non-reviewed content unless fixing an issue.

If this is modifying instructions (be it for a better reproducibility or a different reason), I do not think we should be doing this past submision. This repo has been approved by peer review, we should not be introducing changes (other than bug fixes).
