- First, you need to check to see if you already have SSH key. If you have done `csc231` or are working 
in classes using GitHub classroom, it is likely that you already setup your SSH keys. 
  - Run the following command

```bash
cat ~/.ssh/id_rsa.pub
 

• If you have the SSH keys, you will see the following:
