Without any additional configuration, Sinatra will serve assets in public. For the empty route, you'll want to render the index document.

require 'rubygems'
require 'sinatra'

get '/' do
  File.read(File.join('public', 'index.html'))
end

Routes should return a String which become the HTTP response body. File.read opens a file, reads the file, closes the file and returns a String.
