Git Help PLEASE : I am taking a front-end dev course on udacity.com. Currently learning git and I am stuck. 
I was working on a project and I thought I was following instructions and making a branch called 'include-andras-destinations.  Somehow, this branch is now part of my home directory, but I want to use a different directory to store my git projects and inside the parentheses it should be: (master), like in the attached pic.

Anyone knows how can I reset my default home directory/branch and get rid of "include-andras-destination"?

I would like udacity-git-course folder to be my master. (is that right?) 

If I type:
cd /Users/ruxandravasilescu/Desktop/udacity-git-course
I get:
ruxandravasilescu (include-andras-destinations) udacity-git-course

I don't understand why is that branch always present! Otherwise, git seems set-up okay. I work on a mac.
Please help!
Below is a little infor from my terminal

ruxandravasilescu (include-andras-destinations) ~
$ cd
ruxandravasilescu (include-andras-destinations) ~
$ git init
Reinitialized existing Git repository in /Users/ruxandravasilescu/.git/
ruxandravasilescu (include-andras-destinations) ~
$ pwd
/Users/ruxandravasilescu
ruxandravasilescu (include-andras-destinations) ~
$ git status
On branch include-andras-destinations
Untracked files:
  (use "git add <file>..." to include in what will be committed)

[udacity's git setup on mac looks like this and that's how my terminal initially looked also [1]
