 # Setting up SSH access (optional)
 In order to enable SSH access to git lab, an SSH key pair needs to be used. Learn how to create one [here](https://gitlab.openconn.org/help/ssh/README#generating-a-new-ssh-key-pair) or learn how to use an already existing ssh key [here](https://gitlab.openconn.org/help/ssh/README#locating-an-existing-ssh-key-pair).
 Once you obtain an SSH key pair, learn how to add it to your Gitlab account [here](https://gitlab.openconn.org/help/ssh/README#adding-an-ssh-key-to-your-gitlab-account).
