1. Generate OpenSSH here: https://8gwifi.org/sshfunctions.jsp

2. Add public key to Deploy keys.

3. Add private key to ~/.ssh/ on hosting.

4. Setup ~/.ssh/config on hosting:

Host github.com-<repo>
    Hostname github.com
    IdentityFile=~/.ssh/<private-key>

5. And finally you can clone repo with SSH.

git clone <[email protected]><repo>:<username>/<repo>.git

chmod 700 ~/.ssh
chmod 600 ~/.ssh/*
