3.3 Sitemap creation (primary & secondary IA)

I’m working on a project about [describe your domain/product/idea]. I want to create a sitemap to define primary and secondary navigation. Can you help me with: 1. Proposing a sitemap structure with main sections and subsections. 2. Differentiating between primary vs. secondary IA. 3. Suggesting where to place utility/navigation links (help, profile, settings). 4. Highlighting best practices for sitemap clarity. Format the output as a text-based tree sitemap.
