 # Create a model in lib/user.rb: <code>class User < ActiveRecord::Base; end;</code>
 # Add application code in project root directory and <code>require 'init'</code> in it
 
+h2. Usage with "Sinatra":http://www.github.com/sinatra/sinatra
+
+In your application file (say <code>app.rb</code> sitting in the project root), simply add <code>require 'init'</code> <b>after</b> <code>require 'sinatra'</code>.
+
+A basic sinatra app.rb might look like following (assuming you've got the user model setup and migrated)
+<code>
+require 'sinatra'
+require 'init'
+
+get '/' do
+  User.all.map {|u| u.name}.to_sentence
+end
