+The structure of the sidebar navigation on the site is defined by the site's
+section hierarchy in the `contents` directory. The titles of the pages are
+defined in the front matter of the Markdown files. You can use `title` and
+`linkTitle` to define the title of the page. `title` is used for the page
+title, and `linkTitle` is used for the sidebar title. If `linkTitle` is not
+defined, the `title` is used for both.
