title: Template with TYPO3 v10
body: <p>I would like to do a project with TYPO3 v10 I'm new with this CMS and I need to create different templates for different pages but I don't understand which code I need to change.<br />
  I already install a sitepackage from this site <a href="https://www.sitepackagebuilder.com/" rel="nofollow noreferrer">https://www.sitepackagebuilder.com/</a><br />
  It work well but I need to create my own templates and I want to edit the content of my templates in the back end administration like in the picture.</p>
  <p>I hope I'm clear
  thanks for help :)</p>
