This PR is ready for review.
This PR will restructure main page and getting started page. The main page provides introduction to NERSE without any technical details. The Getting started page has been explained in greater detail for some sections that I was comfortable providing some more insight.
As result of this change some page references were updated due to content or sub-section relocation.
Thank you for this contribution to docs.nersc.gov!
