Post Type file name?

I’ve created a post type but can not view page itself. My post type is called “weeklytips”. However when I try to view the page it defaults to my index.php. I’ve created a weeklytips.php but it still goes to the index.php.

How do I fix this?

add_action( 'init', 'word_post_types' );
function word_post_types() {
	register_post_type( 'weeklytips',
		array(
			'labels' => array(
				'name' => __( 'Weekly Tip' ),
				'singular_name' => __( 'Weekly Tip' ),
				'add_new' => __( 'Add New' ),
				'add_new_item' => __( 'Add New Weekly Tip' ),
				'edit' => __( 'Edit' ),
				'edit_item' => __( 'Edit Weekly Tip' ),
				'new_item' => __( 'New Weekly Tip' ),
				'view' => __( 'View Weekly Tip' ),
				'view_item' => __( 'View Weekly Tip' ),
				'search_items' => __( 'Search Weekly Tip' ),
				'not_found' => __( 'No Weekly Tips found' ),
				'not_found_in_trash' => __( 'No Weekly Tips found in Trash' ),
				'parent' => __( 'Parent Weekly Tip' )
			),
			'public' => true,
			'supports' => array( 'title', 'editor', 'excerpt', 'thumbnail', 'custom-fields' ),
			'taxonomies' => array( 'post_tag', 'category'),
			'rewrite' => true,
			'query_var' => true
		)
	);
	register_taxonomy_for_object_type('category', 'weeklytips');
