+Access to a remote server via public ssh key without password. If you don't have a SSH key pair yet, you can generate it with `ssh-keygen` command on Linux based systems, this key will be added to the `deploy` user `.ssh/authorized_keys` file during installation process so the machine from where running the installer has access to the servers as the `deploy` user.
 The default user is `deploy` but you can [use any user](#using-a-different-user-than-deploy) with sudo privileges.
