Add SSH key to Github from Ubuntu 22.04 LTS

add_ssh_github.md

• Generate SSH key with passphrase and the filename:

ssh-keygen -t ed25519 -C "your_email@example.com"

• Go to the Settings > SSH and GPG keys page of Github
• Click New SSH key
• Copy the SSH key file to your clipboard, here the public key file is in ~/.ssh/id_ed25519.pub:

cat ~/.ssh/id_ed25519.pub

• Paste the SSH key in Github form.

What is a Github form? This documentation doesn't help me. The link Adding a new SSH key is for Windows and I'm using Ubuntu 22.04. This page was the top link for Ubuntu 22.04.
