Ready to clone and publish code in a few minutes.

1. Identify yourself to Git:

   git config --global user.name "Votre Nom"
   git config --global user.email "vous@exemple.fr"

   Copy
2. Create a modern key:

   ssh-keygen -t ed25519 -C "vous@exemple.fr"

   Copy
3. Add it to the agent and the keychain:

   eval "$(ssh-agent -s)"
   ssh-add --apple-use-keychain ~/.ssh/id_ed25519

   Copy
4. Copy the public key to paste it into your Git host's settings:

   pbcopy < ~/.ssh/id_ed25519.pub

   Copy
5. Test the connection:

   ssh -T git@github.com

   Copy
