How do I get to the site building menu?

Hi there. I am a total nube.

The instructions say that I am to access administer/site-building however, the menu bar on my administration page shows only :
Dashboard (View and customize your dashboard.)
Content (Administer content and comments.)
Structure (Administer blocks, content types, menus, etc.)
Appearance (Select and configure your themes.)
People (Manage user accounts, roles, and permissions.)
Modules (Extend site functionality.)
Configuration (Administer settings.)
Reports (View reports, updates, and errors.)
Help (Reference for usage, configuration, and modules.)

So where do I go?

Thank you.

Rob.
