In T4 your page title is taken automatically from the section name. The default page title can be overridden using the Headers and Mastheads content type '01. Page Title and Intro'.

Page titles should be short, no more than 50 characters, and descriptive.

Introductions tell the user what to expect from the page. They can summarise the content and provide an incentive to read on. They are styled differently so they stand out from the main content on the page. They should be less than 50 words.
