First cut at a getting started guide which is more useful than what we had

Trying to reorganize the website so that it's easier to get into the native packager and figure things out.

I need some help here. Spent a good bit of time on this first part to try to get it right. I *think* this may be enough of a start for some help.  This is the last thing holding up the 0.7.0 release.
