 If you clone from this, Git automatically names it `origin` for you, pulls down all its data, creates a pointer to where its `master` branch is, and names it `origin/master` locally; and you can't move it.
 Git also gives you your own `master` branch starting at the same place as origin's `master` branch, so you have something to work from.

+====
+Just like the branch name ``master'' does not have any special meaning in Git, neither does ``origin''. While ``master'' is the default name for a starting branch when you run `git init` which is the only reason it's widely used, ``origin'' is the default name for a remote when you run `git clone`. If you run `git clone -o booyah` instead, then you will have `booyah/master` as your default remote branch.
