how to add pagination to blog posts

i was searching the support forum to remove older posts and add pagination and found no answer so i came up with this fix.

install plugins:

WP-PageNavi
WP Pagenavi Style

edit: index.php

find: (at bottom of page)

</div>
<!-- #content -->

add inline:

<span><?php wp_pagenavi(); ?></span>

looks like:

</article><!-- #post-0 -->

		<?php endif; // end have_posts() check ?>
		<span><?php wp_pagenavi(); ?></span></div>
<!-- #content -->
	</div><!-- #primary -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>

edit: custom.css

Add:

.navigation {
    display: none;
}

got to seetings: Wp Pagenavi Style
choose reqiured style
