+## I can’t clone my git repo
+
+The recommended approach for accessing git repositories in ExCL is to use the SSH protocol instead of the HTTPS protocol for private repositories and either protocol for public repositories. However, both approaches will work with the proper proxies, keys, applications passwords, and password managers in place.
+
+To use the SSH protocol you must first setup SSH keys to the git website (i.e. GitLab, GitHub, and Bitbucket). See [Git - Setup Git access to code.ornl.gov | ExCL User Docs (ornl.gov)](https://docs.excl.ornl.gov/software/git#setup-git-access-to-code.ornl.gov) for details for how to do this for code.ornl.gov. The other Git Clouds have similar methods to add SSH keys to your profile.

+Since the worker nodes are behind a proxy. You must setup an SSH jump host in your `.ssh/config` to access Git SSH servers. See [Git - Git SSH Access | ExCL User Docs (ornl.gov)](https://docs.excl.ornl.gov/software/git#git-ssh-access) to verify that you have setup the proper lines in your SSH Config.
