Hello @kelvynjames,
The easiest way is to edit your logo image and add a text with image editing program like Photoshop.
If you want to display site description along with your logo, you’ll need a child theme to override the header.php file. Download our premade child theme from here. Unzip it. Then you’ll need a copy of the header.php file inside the child theme folder. Then edit this new header.php file with your code editor program. Find this code block:
<div class="col-md-4 col-sm-8 col-xs-12">
<?php if ( get_theme_mod('site_logo') ) : ?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php bloginfo('name'); ?>"><img class="site-logo" src="<?php echo esc_url(get_theme_mod('site_logo')); ?>" alt="<?php bloginfo('name'); ?>" /></a>
<?php else : ?>
<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
<?php endif; ?>
</div>
and replace it with this:
<div class="col-md-4 col-sm-8 col-xs-12">
<?php if ( get_theme_mod('site_logo') ) : ?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php bloginfo('name'); ?>"><img class="site-logo" src="<?php echo esc_url(get_theme_mod('site_logo')); ?>" alt="<?php bloginfo('name'); ?>" /></a>
<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
<?php else : ?>
<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
<?php endif; ?>
</div>
Save changes, then install and activate your child theme either from site admin (/wp-admin) or FTP program.
