How do I customize the menu of my blog?

By default, the primary menu of a blog includes published pages only. Pages are added to the menu automatically. If you want more control over the menu to display pages, posts, outside links, posts of a certain category, and posts with certain tags, you need to create a custom menu and activate it. 

The video below from Edublogs will get you started.
