+
+With **Hugo**, pages are the core of your site. Organize your site like any other Hugo project. **Magic occurs with the nested sections implemention done in v0.22 of hugo (congrats @bep)**.
+
+With docdock, **Each content page composes the menu**, they shape the structure of your website.
+
+To link pages to each other, place them in a folders hierarchy
