Your book will be made up primarily of Book Pages. Other content types such as Content Pages, News, etc. cannot be added to books. You may add the occasional Landing Page as the top-level page or as a chapter-heading page.
Please note, top-level book pages cannot be unpublished without disrupting the structure of the book and potentially other books. Other book pages with child pages must also remain published, or you may disrupt the structure of their book.
When you are logged in, you will see a black admin bar at the upper left side of the page. From this menu, you can easily perform such actions as view content, add content, view and add files, access your Dashboard, log out, etc.
Site Builder Dashboard
The "Dashboard" page contains all of the actions that your role is allowed to perform.
To add a link to a specific location on a different page, follow the same steps for creating a named anchor on the same page.
Anchors point to a specific place within the page. On the page where you want to insert the link, use the Linkit button to find the appropriate page. After using Linkit's autocomplete feature to find the appropriate path to the destination page, you will have to manually add the "#anchorname" to the Link URL.
