-# microbit-chrome
-Prototype chrome addon that exposes the @boardname@'s serial output to webpages. 
-* watch the [demo video](https://vimeo.com/146207766)
-
-# Installation
-See [developer.chrome.com](https://developer.chrome.com/extensions/getstarted#unpacked)
-for instructions on how to install the local version into your chrome browser.
-
-# Requirements
-* Chrome 48 or later.
-
-# Sample page
-The `demo.html` webpage goes along with the
-https://github.com/Microsoft/microbit-touchdevelop/blob/master/examples/tcs34725.cpp
-program. Run `http-server` from this directory, then visit
-http://localhost:8080/demo.html
-(keep in mind that pages served from `file://` cannot open ports).
-
-# Building
-
-Open a command prompt and run the following commands.
-
-````
-npm install
-typings update
-````
