That makes sense. But I think it's a case of getting people to what
they need as quickly as possible (and having the details available
further on, if they need them). The pip documentation is great for
this. Go to the front page, first thing you see is "Quickstart". First
thing that hits your eye on that page is "pip install
SomePackage==1.0".

Maybe that's what the PUG should have - the very first index entry is
"Quick Start". That points to a page that goes:

given my previous arguments, if we have a "Quickstart", I would just have it contain links to the pip & setuptools quickstarts (and wheel too I guess).

setuptools doesn't have a "quickstart" now, but that's part of what I'm doing in my setuptools PR, or you could work on adding one too (that includes reference to your sample project)
