+The navigation organizes your documentation in the left-side nav bar. You can create sections for grouping related content. Each `section` has a name and a list of `contents`. The sections appear in the left-side nav bar in the order that they are listed in `docs.yml`.
 
 In `contents`, list your pages with names and corresponding file paths. The supported file types for pages are `.md` or `.mdx`.
 
 A basic navigation configuration with two sections is shown below. The first section is called `Introduction` and contains a single page called `My Page`. The second section is called **API Reference**. This is a special type of section that's automatically generated by Fern, and you do not need to add any pages to it by hand. For more information, see the [Generate API Reference](/learn/docs/api-references/generate-api-ref) page.

 ### Hiding content
 
+To hide a page or an entire section of your docs, add `hidden: true`. A hidden page or section will still be discoverable using the exact URL, but it will be excluded from search and will not be indexed.
+
+```yaml Example navigation config with additional section {7, 10}
+navigation:
+  - section: Introduction
+    contents:
+      - page: My Page
+        path: ./pages/my-page.mdx
+      - page: Hidden Page
+        hidden: true
+        path: ./pages/my-hidden-page.mdx
+  - section: Hidden Sections
+    hidden: true
+    contents:
+      - page: Another Hidden Page
+        path: ./pages/also-hidden.mdx
+```
+
+## Section overviews
+
+To add an overview page to a section, add a `path` property to the section.
+
+```yaml Example section with an overview {7}
+navigation:
+  - section: Introduction
+    contents:
+      - page: My Page
+        path: ./pages/my-page.mdx
+      - section: Guides
+        path: ./pages/guide-overview.mdx
+        contents:
+          - page: Simple Guide

 ## Nested sections
+
 If you'd like a section to toggle into more sections and pages, you can nest sections within sections. Here's an example:
