A parent page and its children form a section in the sidebar. The parent page is a normal page with its own content, which makes it a good place for an overview.
Example tree
getting-started
├── create-a-page
├── organise-the-page-tree
│ ├── nesting-pages
│ ├── moving-and-reordering
│ └── slugs-and-urls
└── publish-and-preview
Tips
- Keep top-level sections few (five to ten).
- Use the parent page to explain what the section covers and link to its children.
- Avoid single-child sections; merge the child into the parent instead.
