Step 2: In Category Base enter / as follow:
Step 3: Save it and your URLs will be http://website.com/category-slug.
Solution 2:
Although not updated for 2 years but a very flexible plugin. Simple install this plugin: WP No Category Base.
This should work, although not tested. Fill in the categoryID below and set your desired URL in wp_redirect().
<?php$category_id = xx;$category_link = get_category_link( $category_id )wp_redirect( $category_link, 'http://www.website.com/category-slug' ); exit;?>
Remember by the way that wp_redirect() always should be followed by exit;
