  home page. This page is kind of like the table
  of contents of your web site.
• This is labeled as index.html or home.html

• The other pages of the site are called the
  secondary pages.
• They are named whatever you would like them to be
  named. If you have a page about airplanes you
  could name that page airplanes.html. Keep it
  simple!
