As Ember 2.* uses Git when creating a new project, how do I create my own Git repo for my web app's development?

When I run ember new helloworld using ember-cli, it downloads all of the initial building blocks for a new Ember project.

All of it is downloaded using Git. This means that, after finishing running the command for creating a new project, you are basically left with a clone of an official Ember repository.

I would like to create my own Git repository for creating my web app. How would I do this without interfering with or breaking what has been set up by ember-cli? Is it safe to delete the .git directory so I can make my own? Or is there a better/more correct way to do it?
