Template system sucks due to lack of tutorial

@psychicsandra I know this is a months late response but I wanted to at least follow up with some resources that might be helpful:

Learn about the Twenty Twenty-Two Theme and the various full site editing features it unlocks.

Learn about Block Themes and how they allow you to edit all parts of your site with blocks.

Take a course on Learn WordPress about how to build a site with full site editing and the Twenty Twenty-Two Theme.

For you, I’d recommend the course as it really walks you through everything you need to know, including some new blocks, the style systems, and templates!
