add 'about' section to Lock login widget

Is it possible to add an ‘About’ section to Lock login widget? Or, perhaps a link the user could click on that would take them to an About page? I’m creating a website that’s invitation only, and would like to offer information about the site and how to acquire an invitation to users who might stumble upon the site. Is that possible? Thanks.

Lock supports the signUpLink customization]1 that will redirect to a URL you specify, if the user clicks on the Sign Up tab.

var options = {
  signUpLink: ''

If you’d like to make customizations that aren’t currently supported, we recommend using Auth0.js with a custom login page.
