+The goal of `haitch` is to bring the MDN HTML Docs to your editor. By utilizing
+type annotations and inline documentation, this library enables you to write
+apps where you're comfortable (`<insert-your-favorite-editor-here>`). No
+templates and no JavaScript, just Python.
+
+What I want from you is to ruthlessly test the library's API. Don't hold back.
+Be ruthless with your feedback. What's unclear? How could it be improved? I'll
+be there to answer questions and gather feedback for the future documentation.
+Check out the milestone link for more details.
