+# How to contribute to xterm.js
+
+- [Opening issues for bug reports or feature requests](#opening-issues)
+- [Contributing code](#contributing-code)
+
+## Opening issues
+
+The preferred way to report bugs or request features is to use
+[GitHub issues](http://github.com/sourcelair/xterm.js/issues). Before
+opening an issue, read these pointers.
+
+### Opening issues effectively
+
+- Include information about **the browser in which the problem occurred**. Even
+  if you tested several browsers, and the problem occurred in all of them,
+  mention this fact in the bug report. Also include browser version numbers and
+  the operating system that you're on.
+
+- Mention which release of xterm.js you're using. Preferably, try also with
+  the current HEAD of the master branch, to ensure the problem has not already been
+  fixed.
+
+- Mention precisely what went wrong. What did you expect to happen? What happened instead? Describe the
+  exact steps a maintainer has to take to make the problem occur.
+
+- If the problem can not be reproduced in the [demo of xterm.js](README.md#demo), please provide an HTML document that demonstrates the problem.
+
+- Be polite. Issues with an indignant or belligerent tone tend to be moved to the
+  bottom of the pile.
+
+## Contributing code
+
+- Make sure you have a [GitHub account](https://github.com/join)
+- Fork [xterm.js](https://github.com/sourcelair/xterm.js/)
+  ([how to fork a repo](https://help.github.com/articles/fork-a-repo))
+- Make your changes
+- If your changes are easy to test or likely to regress, add tests. Tests go into `test`, directory.
+- Follow the general code style of the rest of the project (see below).
+- Submit a pull request
+([how to create a pull request](https://help.github.com/articles/fork-a-repo)).
+  Don't put more than one feature/fix in a single pull request.
+
+By contributing code to xterm.js you
+
+ - agree to license the contributed code under xterm.js' [MIT
+   license](LICENSE).
+
+ - confirm that you have the right to contribute and license the code
+   in question. (Either you hold all rights on the code, or the rights
+   holder has explicitly granted the right to use it like this,
+   through a compatible open source license or through a direct
+   agreement with you.)

-# xterm.js — xterm, in the browser
+# [![xterm.js logo](logo.png)](https://xtermjs.org)

-Xterm.js is a full xterm clone, written completely in JavaScript.
+[![xterm.js build status](https://api.travis-ci.org/sourcelair/xterm.js.svg)](https://travis-ci.org/sourcelair/xterm.js) [![Coverage Status](https://coveralls.io/repos/github/sourcelair/xterm.js/badge.svg)](https://coveralls.io/github/sourcelair/xterm.js) [![Gitter](https://badges.gitter.im/sourcelair/xterm.js.svg)](https://gitter.im/sourcelair/xterm.js?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge)

-Xterm.js supplies a modular, event-based interface that lets developers build addons and themes that augment  the experience of running a fully-featured terminal inside the browser.
+Xterm.js is a terminal front-end component written in JavaScript that works in the browser.

-Xterm.js serves as foundation for the terminal found at www.sourcelair.com.
+It enables applications to provide fully featured terminals to their users and create great development experiences.

-![xterm.js screenshot](docs/screenshot.png)
+## Features
+- **Text-based application support**: Use xterm.js to work with applications like `bash`, `git` etc.
+- **Curses-based application support**: Use xterm.js to work with applications like `vim`, `tmux` etc.
+- **Mouse events support**: Xterm.js captures mouse events like click and scroll and passes them to the terminal's back-end controlling process
+- **CJK (Chinese, Japanese, Korean) character support**: Xterm.js renders CJK characters seamlessly
+- **IME support**: Insert international (including CJK) characters using IME input with your keyboard
+- **Self-contained library**: Xterm.js works on its own. It does not require any external libraries like jQuery or React to work
+- **Modular, event-based API**: Lets you build addons and themes with ease

-### Contribution and License Agreement
+## What xterm.js is not
+- Xterm.js is not a terminal application that you can download and use on your computer
+- Xterm.js is not `bash`. Xterm.js can be connected to processes like `bash` and let you interact with them (provide input, receive output)
+
+## Real-world uses
+Xterm.js is used in several world-class applications to provide great terminal experiences.

+
+Do you use xterm.js in your application as well? Please [open a Pull Request](https://github.com/sourcelair/xterm.js/pulls) to include it here. We would love to have it in our list.
+
+## Browser Support
+
+Since xterm.js is typically implemented as a developer tool, only modern browsers are supported officially. Here is a list of the versions we aim to support:
+
+- Chrome 48+
+- Edge 13+
+- Firefox 44+
+- Internet Explorer 11+
+- Opera 35+
+- Safari 8+
+
+Xterm.js works seamlessly in Electron apps and may even work on earlier versions of the browsers but these are the browsers we strive to keep working.
+
+## Demo
+
+### Linux or macOS
+
+Run the following commands:
+
+```
+$ npm install
+$ npm start
+```
+
+Then open http://0.0.0.0:3000 in a web browser.
+
+### Windows
+
+First, ensure [node-gyp](https://github.com/nodejs/node-gyp) is installed and configured correctly, then run these commands.
+
+Note: Do not use ConEmu, as it seems to break the demo for some reason.
+
+```
+> npm install
+> npm start
+```
+
+Then open http://127.0.0.1:3000 in a web browser.
+
+## Getting Started
+
+To start using xterm.js on your browser, add the `xterm.js` and `xterm.css` to the head of your html page. Then create a `<div id="terminal"></div>` onto which xterm can attach itself.
+```html
+<!doctype html>
+  <html>
+    <head>
+      <link rel="stylesheet" href="bower_components/xterm.js/dist/xterm.css" />
+      <script src="bower_components/xterm.js/dist/xterm.js"></script>
+    </head>
+    <body>
+      <div id="terminal"></div>
+      <script>
+      	var term = new Terminal();
+        term.open(document.getElementById('terminal'));
+        term.write('Hello from \033[1;3;31mxterm.js\033[0m $ ')
+      </script>
+    </body>
+  </html>
+```
+Finally instantiate the `Terminal` object and then call the `open` function with the DOM object of the `div`.
+
+## Addons
+
+Addons are JavaScript modules that attach functions to the `Terminal` prototype to extend its functionality. There are a handful available in the main repository in the `dist/addons` directory, you can even write your own (though they may break when the internals of xterm.js change across versions).
+
+To use an addon, just include the JavaScript file after xterm.js and before the `Terminal` object has been instantiated. The function should then be exposed on the `Terminal` object:
+
+```html
+<script src="node_modules/dist/xterm.js"></script>
+<script src="node_modules/dist/addons/fit/fit.js"></script>
+```
+
+```js
+var xterm = new Terminal();
+// init code...
+xterm.fit();
+```
+
+## Releases
+
+Xterm.js follows a monthly release cycle roughly.
+
+The existing releases are available at this GitHub repo's [Releases](https://github.com/sourcelair/xterm.js/releases), while the roadmap is available as [Milestones](https://github.com/sourcelair/xterm.js/milestones).
+
+## Development and Contribution
+
+Xterm.js is maintained by [SourceLair](https://www.sourcelair.com/) and a few external contributors, but we would love to receive contributions from everyone!
+
+To contribute either code, documentation or issues to xterm.js please read the [Contributing document](CONTRIBUTING.md) beforehand. The development of xterm.js does not require any special tool. All you need is an editor that supports JavaScript/TypeScript and a browser. You will need Node.js installed locally to get all the features working in the demo.

-Welcome to xterm.js's documentation!
-====================================
-
-This is the documentation for xterm.js. Xterm.js is a full xterm clone, written completely in JavaScript.
-
-Xterm.js supplies a modular, event-based interface that lets developers build addons and themes that augment 
-the experience of running a fully-feature terminal inside the browser.
-
-Xterm.js serves as the foundation for the terminal found at www.sourcelair.com.

-Getting started
-^^^^^^^^^^^^^^^

-.. code-block:: javascript
-    
-   var term = new Terminal(),
-       url = 'ws://docker/containers/mycontainer/attach/ws/?stdin=1&stdout=1&stderr=1&logs=1',

-   socket.onmessage = function (e) {
-       term.write(e.data);

-Contents

-The standard way to create a terminal-based application with xterm.js is to work with its events and

+- open xterm
