How I Fixed a .git within a .git Issue

gistfile-fixgitissue.txt

I was going through a tutorial and had a project that had git repo initialized. 
I added a project from a zip file that had its own .git and .gitignore file. This caused problems when I wanted to commit 
changes to this file. the diagram below shows the representation

Diagram:
my_project
  |
  |----- .git
  |----- .gitignore
  |
  ------ new_directory
              |
              |-------- .git
              --------- .gitignore

How I fixed this issue:
1. Delete the .git and .gitignore file from the new_directory
2. Navigate back to my_project.
3. Renamed new_directory to new_directory_x.
Side Note: If you try to add to the git stage the newly renamed new_directory_x then you will see the following error:

fatal: Unable to create '/Users/nick_x/software-projects/udemy-complete-angular-master-class/.git/index.lock': File exists.

If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
process is running and remove the file manually to continue.

4. Run the following command from the terminal:  rm -f ./.git/index.lock
5. Now you can add and commit files from the new_directory_x to your git repository.
