Couldn't Get to Work

Read me file says if posts won’t sort you need to change query to “$sticky_query = new WP_Query( array( ‘post__in’ => get_option(‘sticky_posts’), ‘orderby’ ==> ‘post__in’ ) );”

But there’s no instruction in where this goes. Tried to add to the plugin thru editor but kept getting syntax errors.

I had high hopes because all the other sticky post order plugins are outdated.

Maybe there will be an update?
