 == The Bleeding Edge
+=== With Bundler
+If you want to run your application with the latest Sinatra, using
+{Bundler}[http://gembundler.com/] is the recommend way.
 
+First, install bundler, if you haven't:
+
+  gem install bundler
+
+Then, in you project directory, create a +Gemfile+:
+
+  source :rubygems
+  gem 'sinatra', :git => "git://github.com/sinatra/sinatra.git"
+  
+  # other dependencies
+  gem 'haml'                    # for instance, if you use haml
+  gem 'activerecord', '~> 3.0'  # maybe you also need ActiveRecord 3.x
+
+Note that you will have to list all your applications dependencies in there.
+Sinatra's direct dependencies (Rack and Tilt) will however be automatically
+fetched and added by Bundler.
+
+Now you can run your app like this:
+
+  bundle exec ruby myapp.rb
+
