 It is best practice to use [Git over SSH instead of Git over HTTP](https://git-scm.com/book/en/v2/Git-on-the-Server-The-Protocols).
 In order to use SSH, you will need to:
 
-1. [Create an SSH key pair](#creating-your-ssh-key-pair) on your local computer.
-1. [Add the key to GitLab](#adding-your-ssh-public-key-to-gitlab).
+1. Create an SSH key pair
+1. Add your SSH public key to GitLab
