How to understand DRUPAL structure?

Question

CMS

Which file to edit to change the allowed ABOUT page? it just has page.tpl.php and nothing else

Answer 1

Oh bro, you can see with Drupal for the first time working, it's not wordpress for you, everything is more difficult here.
For each page, you need to create a separate tpl. The theme developer module will tell you how to call it

Answer 2

You copy page.tpl.php, rename it to page--about.tpl.php and pick the html there for your about page.
Start with the easiest, make pages on Panels :D
