+## Git SSH Deploy Keys and Tokens
+
+All of the clone URLs are HTTPS clone URLs.
+
+To use SSH clone URLs, you should update your git credentials:
+
+```bash
+git config --global url."ssh://git@github.com/example-org/".insteadOf "https://github.com/example-org/"
+```
+
+This will add an entry like this to your `.gitconfig`:
+
+```ini
+[url "ssh://git@github.com/example-org/"]
+    insteadOf = https://github.com/example-org/
+```
+
+For more info see
+[The Git Credentials Cheat Sheet](https://coolaj86.com/articles/vanilla-devops-git-credentials-cheatsheet/)
+at <https://coolaj86.com/articles/vanilla-devops-git-credentials-cheatsheet/>.
