Query posts function

Hi I’m trying to custmoise my home.php file (set as part of a child theme – https://pastebin.com/nghyKsb8)

I only want posts in the catgeory home to be displayed, I thought it was simply to add

<?php if ( have_posts(<strong>cat='home'</strong>) ) : ?>

                        <?php /* Start the Loop */ $ink_count = 0; $ink_row_count=0 ?>
                        <?php while ( have_posts() ) : the_post();
                                 if ($ink_count == 0 ) {echo "<div class='row-".$ink_row_count." row'>";}
                        ?>

but to no avail
