- * Twenty Fifteen functions and definitions
- *
- * Set up the theme and provides some helper functions, which are used in the
- * theme as custom template tags. Others are attached to action and filter
- * hooks in WordPress to change core functionality.
- *
- * When using a child theme you can override certain functions (those wrapped
- * in a function_exists() call) by defining them first in your child theme's
- * functions.php file. The child theme's functions.php file is included before
- * the parent theme's file, so the child theme functions would be used.
- *
- * @link https://codex.wordpress.org/Theme_Development
- * @link https://codex.wordpress.org/Child_Themes
- *
- * Functions that are not pluggable (not wrapped in function_exists()) are
- * instead attached to a filter or action hook.
- *
