I create a new repository:

git init
echo "# MESSAGE" >> README.md
git add README.md
git commit -m "first commit"

Then I want to push my commit to the empty remote repository created on github so I have to set remote.

What is difference between using following commands ? :

git remote add origin [email protected]:User/UserRepo.git
git remote set-url origin [email protected]:User/UserRepo.git

At the end I perform push:

git push -u origin master

What happens when I call git remote set-url origin just after git init? Does git remote set-url origin create origin? If origin already exists after git init there is no difference between using those commands in my scenario, right?
