Git is a distributed versioning solution, and this causes a lot of misunderstanding at times.
What Angular is doing for you is actually turning your project directory into a git working directory. What this means is that you can now open a CLI and type git <anything>
with git actually doing what you are asking it to do. If you didn't ask Angular to do so, you could have open a terminal in your project directory and type git init
to get to the same result.
Your git repository can now be linked to one or more remote repositories. These can be on your machine, on a USB stick, on a shared physical drive in your organization, on a CD ROM, on your old MP3 player or even in cloud, for instance on GitHub or BitBucket.
Angular does not create a remote repository for you, only turns your project folder into a local working repository.
You'll have to create a remote repository yourself, then, in your local, link it as remote:
git remote add origin <URL to your remote>
If you are using GitHub, check out their guide.
As this question is getting asked over and over again, I hope this answer would help git newbies to better understand what is going on.
