Does running git init twice initialize a repository or reinitialize an existing repo?

Question

What happens to an existing git repository when you issue git init again?

I created a repository with git init. Created a file, add, commi

Answer 1

it's mean that you already initialized the git. because you already upload a file on github from this path. you check the path then a folder is created by name of .git. That is why you don't requried again to initialized git. you can go to direct next step

git add .
