Getting started
The first hour: sections, pages and putting something on one.
Menus and Nesting
The address has two parts and cannot show nesting. The menu can, and it is what a reader sees.
Your First Page
A page has no content of its own. Everything on it is a component you place — including the plain text.
Sections and Addresses
A section is a mini-site: its own design, its own logo, its own contacts. Everything else follows from that.
