Check if Git is installed. If not, stop and say so. 2. Check if an SSH key (ed25519) exists. - If not, generate one. 3. Show the PUBLIC SSH key (.pub) exactly as-is. 4. Ask the user to add the key at: https://github.com/settings/keys and WAIT until they confirm. 5. Test SSH authentication: ssh -T git@github.com - If authentication fails, stop and explain why. 6. Clone the repository using SSH. 7. Enter the repository directory. 8. Verify the remote: git remote -v - It MUST be SSH. 9.
