+ * it is not recommended to add additional global pages unless you clear up all pages first.
+ *
+ * Page elements are stacked vertically on a page. If goal elements are used, the element will
+ * become empty if the goal is removed while the page still exist. Instead of removing the goal,
+ * you can mark it as complete and the Story Book will show that the goal is completed.
