You should work through linkgit:gittutorial[7] before reading this tutorial.
The goal of this tutorial is to introduce two fundamental pieces of
-git's architecture--the object database and the index file--and to

Let's start a new project and create a small amount of history:

the same data twice (since identical data is given an identical SHA1

that would change the object's name as well). The 7 char hex strings
here are simply the abbreviation of such 40 character long strings.
Abbreviations can be used everywhere where the 40 character strings

it was created and the name of the person performing the commit.

command. Don't copy the 40 hex digits from this example but use those
from your own version. Note that you can shorten it to only a few
characters to save yourself typing all 40 hex digits:
hello world
