Add a StaticPage controller, using rails generate controller...
created all 3: 1.home,2.help,3.about; 1. tests 2. update config/routes.rb 3. update static_pages_controller 4.updated/created views with correct text to pass test
application.html.erb removed for testing. views for home, help, & about updated to each have full HTML structure (intentionally redundant, to learn how to make code more DRY)
altered views to use provide(:title, 'Home') etc, as substitutions in the <title> tags -- to make all the views similar, so that we can make more DRY.
Returned application.html.erb. In 3 views: left provide(:title, 'foo'), left content inside individual <body> tags, Removed redundant HMTL from 3 views.
removed a folder
altered <h1> tags in views
