  -Escape!
  +
  +html2js is a tool to convert packages of HTML imports to JavaScript modules.
  +
  +## Goals
  +
  +The goal of the tool is to allow Polymer and Polymer elements to be converted to JavaScript modules with as litle intervention as possible. The tool will try to strike a balance between supporting the general semantics of HTML imports and generating the idiomatic JavaScript that would have been written without them.
  +
  +## Status
  +
  +html2js is under heavy construction and only barely usable on the Polymer core library as of now. We are still fixing issues and adding support for Polymer elements.
