Hello,
Thanks for submitting a question about adding a blog to the bottom of the homepage. In BoldGrid, pages are separate from blog posts or pages that contain blog posts. To combine these by adding posts to a page requires theme editing.
The first thing to do is set up a child theme. That is the best way to modify a theme. Then a query can be used to grab recent posts. The basic WordPress post loop looks like this:
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
This code can be added to a page template, and then this page template can be used as your home page.
Best,
Christopher M.
