Admin sidebar in 3.5.1

I am brand-new to WordPress. I have been tasked by my supervisor to learn WordPress and document how it is used in our site. I have some instructions for a particular plugin that say to “Navigate to the HTTPS settings page in the admin sidebar in the dashboard.” I cannot find the admin sidebar. I am logged in as the designated administrator. The sidebar of the dashbar contains these items: Posts, Media, Links, Pages, Comments, Forms, Appearance, Profile, Tools, Calendar. Any help is appreciated. Thanks.
