-An application shell for building a simple, command-line web server for productive web development.
+An application shell for building a simple, command-line web server for productive web development. It contains no middleware of its own but will load default-stack unless you specify otherwise.
 
 It is trivial is bundle and deploy with your project. Also deploys to heroku well for demo projects.
