+## Document collections
+
+By default, the navigation and search include normal [pages](https://jekyllrb.com/docs/pages/).
+Instead, you can also use [Jekyll collections](https://jekyllrb.com/docs/collections/) which group documents semantically together.
+
+For example, put all your documentation files in the `_docs` folder and create the `docs` collection:
+```yaml
+# Define Jekyll collections
+collections:
+  # Define a collection named "docs", its documents reside in the "_docs" directory
+  docs:
+    permalink: "/:collection/:path/"
+    output: true
+
+just_the_docs:
+  # Define which collections are used in just-the-docs
+  collections:
+    # Reference the "docs" collection
+    docs:
+      # Give the collection a name
+      name: Documentation
+      # Exclude the collection from the navigation
+      # Supports true or false (default)
+      nav_exclude: false
+      # Exclude the collection from the search
+      # Supports true or false (default)
+      search_exclude: false
+```
+
+You can reference multiple collections.
+This creates categories in the navigation with the configured names.
+```yaml
+collections:
+  docs:
+    permalink: "/:collection/:path/"
+    output: true
+  tutorials:
+    permalink: "/:collection/:path/"
+    output: true
+
+just_the_docs:
+  collections:
+    docs:
+      name: Documentation
+    tutorials:
+      name: Tutorials
+```
