title: Why commits by github don't show 'verified' (signed commits)?
body: <p>I got the git commits from my local repo to show 'verified' on github, by setting up the gpg key.  </p>
  
  <p>But why my commits by github (while I am on github) don't show up as 'verified'?  It shows nothing, indicating github sees them as unverified commits. Is this expected or maybe I need to configure something on github?</p>
  
  <p>Thanks.</p>
