I've moved it here to work on cleaning it up and preparing it to be added to the Drupal handbook.

While the page.tpl.php file of your theme is the "highest level" template which controls the layout of your site overall and by default is consistent through all the pages of your site, there are a number of more specific template files that control how sub-elements of pages are themed "within" page.tpl.php, such as the different content that appears on each page throughout the s

One interesting method of making a home page that offers a mix of easy editing of static fields, plus the ability to embed blocks and other dynamic content, is by making your front page using CCK.
