Make a blog in a php script

<style type="text/css">
<link href="style.css" rel="stylesheet" type="text/css">
</style>
<?php /* Template Name: WPBeginnerT1 */ ?>

<?php get_header(); ?>
<?php get_footer(); ?>

This is my code so far for a .php, it works great and it fetches the header and footer. What I now want to do is build blog to show posts for a staff blog.

What code will I need to add to do this?
