"Get Started"

After you created a repository on Bitbucket, and you click your newly created repository, you receive a message like:

Import an existing repository

• You already have a Git repository on your computer. Let's publish it to Bitbucket.
  cd /path/to/my/repo
  git remote add origin ssh://git@bitbucket.org/Locolabo/schoenen-lorenz.git
  git push -u origin --all # to push changes for the first time

But In my case, I'm new to git, so the above command didn't work.
Here it is simply explained how to get started from scratch easely:
