+The specified `nav_order` parameters on a site should be all integers or all strings.
+Pages without a `nav_order` parameter are ordered alphabetically by their `title`,
+and appear after the explicitly-ordered pages at each level.
+To sort all Capital letters before lowercase letters,
+add `nav_sort: case_sensitive` in the configuration file.
