GIT: fatal: 'master' does not appear to be a git repository

Question

I was pushing my master branch to my GIT repo and go this error

  fatal: 'master' does not appear to be a git repository

On the advice of a stack question I typed

  git remote -v

and got

  heroku    https://git.heroku.com/peaceful-cove-8372.git (fetch)
  heroku    https://git.heroku.com/peaceful-cove-8372.git (push)
  origin    https://github.com/SimonWalsh1000/breathe.git (fetch)
  origin    https://github.com/SimonWalsh1000/breathe.git (push)

I then typed

   simonalice$ git push -u origin master

And it worked but said

   Branch master set up to track remote branch master from origin.

I am very new to GIT and I am not fully sure what has happened. I would be very grateful if someone could explain this sequence to me. I haven't been able to get clear answers. Is my master branch now, the master branch in GIT or is it some clone?

Many thanks

Branch master set up to track remote branch master from origin.

Do a git config --local -l

You will see that the local branch master is set to track the upstream branch origin/master

See "Difference between git checkout --track origin/branch and git checkout -b branch origin/branch".

It would be like you did:

git config branch.master.remote origin
git config branch.master.merge refs/heads/branch

The first push needs that upstream information: see "Why do I need to explicitly push a new branch?".
