Integration for Sally Theme

I am trying to implement this plugin for my theme, but I’m not sure what code to replace.

Here is what I have in my author.php file:

<?php
/**
 * @package sally
 * @since sally 1.0
 */
get_header();
?>

<div class="container container-content">
	<div class="row">

		<div class="col-md-8 sl-feedgrid">
			<div class="bb-author">
				<?php echo get_avatar( get_the_author_meta('ID'), 140 ); ?>
				<h4><?php _e('About','sally') ?> <?php the_author(); ?></h4>
				<span class="mini-tag"><?php _e('has published', 'sally'); ?> <?php the_author_posts(); ?> <?php _e('posts', 'sally'); ?></span>
				<p class="author-bio"><?php the_author_meta('description'); ?></p>
				<div class="mini-icons hidden-xs"><?php sally_author_icons(); ?></div>
			</div> <!-- /bb-author-->

			<h3 class="sec-title sec-l"><span><?php printf( __( 'Posts By %s', 'sally' ), '<a class="url vcard fn n" href="' . esc_url( get_author_posts_url( get_the_author_meta( "ID" ) ) ) . '" title="' . esc_attr( get_the_author() ) . '" rel="me">' . get_the_author() . '</a>' ); ?></span></h3>

			<div id="sl-main-feed" class="row">
				<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
				<div class="sl-entry <?php if ( !is_sticky() ) { echo "col-md-6"; } else { echo "col-md-12"; } ?>">
					<?php get_template_part('content'); ?>
				</div>
				<?php endwhile; endif; ?>
			</div> <!-- /sl-main-feed-->

			<?php sally_content_nav(); ?>
		</div> <!-- /sl-feedgrid-->

		<?php get_sidebar(); ?>
	</div>
</div> <!-- /sl-container-->

<?php get_footer(); ?>

Any ideas?
