How to clone a repository with SSH key
Assuming that you have already created your key and it is everything working you may want to clone a repository, but since you have your keys set in place it gives you an error, something like "fatal: Authentication failed for ....".
Here cause you must define the SSH key that you want to use, or git is unable to know who you are. Doing it is pretty simple.
You just have to define your SSH informations while doing the clone, before the path of your project, so you should not use http, here you have an example.
git clone git@git-mycompany:/Path/Of/Your/Project
