+When pruning is enabled, only the visible navigation items are included in the 
+rendered HTML, __reducing the size of the built site by 33% or more__. Add the 
+following lines to `mkdocs.yml`:
+
+``` yaml
+theme:
+  features:
+    - navigation.prune # (1)!
+```
+
+1.  This feature flag is not compatible with
+    [`navigation.expand`][navigation.expand], as navigation expansion requires
+    the complete navigation structure.
+
+This feature flag is especially useful for documentation sites with 100+ or even
+1,000+ of pages, as the navigation makes up a significant fraction of the HTML.
+Navigation pruning will replace all expandable sections with links to the first
+page in that section (or the section index page).
