Barebones Git
Secondly...
Let's start setting up in an empty folder (I'll name it gittut)
The magic starts with initializing a Git repository
C:\...\>mkdir gittut
C:\...\>cd gittut
C:\...\gittut>git init
It means that the folder is ready for some version control action! The only visible difference would be that there is be .git folder created in the directory which is hidden by default. The takeaway point is that any location containing a .git folder means one or more (generally all) files have versions which Git is handling. Let's create a text file named 'my.txt'.
C:\...\gittut>more my.txt
First line, nothing more!!
the current folder would look like this...
Git still wouldn't know that something new has been added. Technically, it hasn't started tracking any files.
C:\...\gittut>git status
On branch master
Initial commit
Untracked files:
(use "git add <file>..." to include in what will be committed)
my.txt
nothing added to commit but untracked files present (use "git add" to track)
git status gives, well, the current status of the folder.
