I am trying to configure my git (git config). I type in ssh -T git@github.com to see if I set everything up. I am getting an error message

Question

keeganomel@Keegans-MBP ~ % ssh -T git@github.com
/Users/keeganomel/.ssh/config: line 3: Bad configuration option: usekeychain
/Users/keeganomel/.ssh/config: terminating, 1 bad configuration options

What have I done wrong? How can I remedy this?

I was expecting to verify that the finger print in the message would match the Github's RSA public key fingerprint.
