Where to register SSH key in Git?

Question

git

I read an article on the integration of Git and Sublime on Habré. It seems to be integrated, but nothing is sent to the repository. I suspect that after
git init
git remote add origin [email protected]:Suliman/dapp.git
git Add .
you need to register the ssh key somewhere, but where ??
For reps I use: https://bitbucket.org
OS Windows
