The Missing Picture

Explanation of what picture is missing

I am starting to use GIT locally.  I was having difficulty understanding how to 
"checkout" the files into different directories.  One for testing, and one for 
"production".  I think I am  just now getting the point of my misunderstanding 
and starting to understand what the various git commands do.  I was  unable to 
figure it out easily  from the documentation or anything I could find on the 
web.  I finally drew the picture of a hub and spokes.  I wish I could include 
it here.

The point is that the Clone repository spokes talk to the hub respository, but 
the spokes cannot speak to each other.  Thats why you have to push a repository 
to the hub, and then pull the hub out to a spoke.

Do I have the concept right?  So what I need to do is  to create a hub on my 
local computer if I want to operate only locally.  I read that in some document, 
but I had a hard time figuring out the business of understanding exactly what.

git init --bare

was all about.  Slowly the dawn dawns, I think.

Most if not all of the documentation is written as if you understand this concept.
I never saw it explained, and I never saw the picture.
