 # Tests for exclusion Exclusion
 
+Pages excluded from the main navigation can have parents and children. Navigation to and between excluded pages can be supported by the auto-generating list of child pages inserted at the bottom of each page, and by links to parents in the breadcrumbs at the top of each page.
+
+The following tests cover all combinations of excluded and included pages for the top level, child pages, and grandchild pages. The last binary digit in a page title indicates whether the page is included (1) or excluded (0); preceding digits refer to its parent and grandparent.

 # Order
 
+The value of `nav_order` can be numbers (integers, floats) and/or strings. The following tests illustrate their effects.
+
 - [Default](default/), using `title` instead of `nav_order` fields.
 - [Strings](strings/), lexicographically ordered, possibly case-insensitively.
 - [Integers](integers/), numerically ordered.
