Sitepress was originally designed to be embedded in Rails. To get started add this line to your application's Gemfile:

gem 'sitepress-rails'

And then bundle it into your application:

$ bundle

Then create the directory app/content/pages and add the page below to hello.html.erb:

$ echo "<h1>Hello</h1><p>It is <%= Time.now %> o'clock</p>" > app/content/pages/hello.html.erb

Point your browser to and if all went well you should see the page you just created.
