It covers the basics of static routes and then dives into dynamic routes for cases where route segments are unknown at development time, such as IDs, names, or slugs. The tutorial includes code examples, setup instructions for a new Next.js project, and best practices for creating dynamic segments. It also defines what a slug is and its importance for SEO.
