How display summary of posts not full text?

i think you want to say see more on click,that is excerpt,,
go on function.php of your theme and paste the below code

function custom_excerpt_length( $length ) {
return 20;
}
add_filter( ‘excerpt_length’, ‘custom_excerpt_length’, 999 );

function new_excerpt_more( $more ) {
return ‘ <p>Read more</p>’;
}
add_filter( ‘excerpt_more’, ‘new_excerpt_more’ );

then go to your template page and paste the below code where your post originally lies

<?php the_excerpt();?>
you can change the above code as required
i think it will help you

Ok I add <?php the_excerpt();?> in content.php and works now. I can use “Read more” but be enough for now. First time I read somewhere need to add in home.php this code.

Thank you
