title: Creating keycloak custom theme
body: <p>I have in my UI three views:</p>
  
  <ul>
  <li>starting page (with links to registration and login pages)</li>
  <li>login page</li>
  <li>registration page</li>
  </ul>
  
  <p>I don't know how to display firstly the starting page. My starting page in my custom theme is the login page (my-site/auth). How to change this?</p>
  
  <p>I tried with request parameters, by I can't get the url params in .ftl template pages. </p>
  
  <p>How to extend the server by endpoint or read url param in template?</p>
  
  <p>Maybe there is another solution... Thank you!</p>
