+Xterm.js is a terminal front-end component written in JavaScript that works in the browser.
+
+It enables applications to provide fully featured terminals to their users and create great development experiences.
 
 ## Features
-
-- **Terminal apps just work**: Xterm.js works with most terminal apps such as `bash`, `vim`, and `tmux`, including support for curses-based apps and mouse events.
-- **Performant**: Xterm.js is *really* fast, it even includes a GPU-accelerated renderer.
-- **Rich Unicode support**: Supports CJK, emojis, and IMEs.
-- **Self-contained**: Requires zero dependencies to work.
-- **Accessible**: Screen reader and minimum contrast ratio support can be turned on.
-- **And much more**: Links, theming, addons, well documented API, etc.
+- **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
 
 ## 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).

 ### Addons
 
-⚠️ *This section describes the new addon format introduced in v3.14.0, see [here](https://github.com/xtermjs/xterm.js/blob/3.14.2/README.md#addons) for the instructions on the old format*
+Addons are JavaScript modules that extend the `Terminal` prototype with new methods and attributes to provide additional functionality. There are a handful available in the main repository in the `src/addons` directory and you can even write your own, by using xterm.js' public API.
 
-Addons are separate modules that extend the `Terminal` by building on the [xterm.js API](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts). To use an addon, you first need to install it in your project:
+To use an addon, just import the JavaScript module and pass it to `Terminal`'s `applyAddon` method:
 
-```bash
-npm i -S xterm-addon-web-links
+```javascript
+import { Terminal } from xterm;
+import * as fit from 'xterm/lib/addons/fit/fit';
+
+
+Terminal.applyAddon(fit);
+
+var xterm = new Terminal();  // Instantiate the terminal
+xterm.fit();                 // Use the `fit` method, provided by the `fit` addon
 ```
 
-Then import the addon, instantiate it and call `Terminal.loadAddon`:
+#### Importing Addons in TypeScript
 
-```ts
+There are currently no typings for addons if they are accessed via extending Terminal prototype, so you will need to upcast if using TypeScript, eg. `(<any>xterm).fit()`.
+
+Alternatively, you can import addon function and enhance the terminal on demand. This would have better typing support and is friendly to treeshaking. E.g.:
+
+```typescript
 import { Terminal } from 'xterm';
-import { WebLinksAddon } from 'xterm-addon-web-links';
+import { fit } from 'xterm/lib/addons/fit/fit';
+const xterm = new Terminal();
 
-const terminal = new Terminal();
-// Load WebLinksAddon on terminal, this is all that's needed to get web links
-// working in the terminal.
-terminal.loadAddon(new WebLinksAddon());
+// Fit the terminal when necessary:
+fit(xterm);
 ```
 
-The xterm.js team maintains the following addons, but anyone can build them:
+#### Third party addons
 
-- [`xterm-addon-attach`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-attach): Attaches to a server running a process via a websocket
-- [`xterm-addon-fit`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-fit): Fits the terminal to the containing element
-- [`xterm-addon-search`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-search): Adds search functionality
-- [`xterm-addon-web-links`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-web-links): Adds web link detection and interaction
+There are also the following third party addons available:

 ## Browser Support
 
-Since xterm.js is typically implemented as a developer tool, only modern browsers are supported officially. Specifically the latest versions of *Chrome*, *Edge*, *Firefox*, and *Safari*.
+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:
 
-Xterm.js works seamlessly in [Electron](https://electronjs.org/) apps and may even work on earlier versions of the browsers. These are the versions we strive to keep working.
+- Chrome latest
+- Edge latest
+- Firefox latest
+- Safari latest
+- IE11
 
-### Node.js Support
-
-We also publish [`xterm-headless`](https://www.npmjs.com/package/xterm-headless) which is a stripped down version of xterm.js that runs in Node.js. An example use case for this is to keep track of a terminal's state where the process is running and using the serialize addon so it can get all state restored upon reconnection.
-
-## API
-
-The full API for xterm.js is contained within the [TypeScript declaration file](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts), use the branch/tag picker in GitHub (`w`) to navigate to the correct version of the API.
-
-Note that some APIs are marked *experimental*, these are added to enable experimentation with new ideas without committing to support it like a normal [semver](https://semver.org/) API. Note that these APIs can change radically between versions, so be sure to read release notes if you plan on using experimental APIs.
-
-## Releases
-
-Xterm.js follows a monthly release cycle roughly.
-
-All current and past releases are available on this repo's [Releases page](https://github.com/sourcelair/xterm.js/releases), you can view the [high-level roadmap on the wiki](https://github.com/xtermjs/xterm.js/wiki/Roadmap) and see what we're working on now by looking through [Milestones](https://github.com/sourcelair/xterm.js/milestones).
-
-### Beta builds
-
-Our CI releases beta builds to npm for every change that goes into master. Install the latest beta build with:
-
-```bash
-npm install -S xterm@beta
-```
-
-These should generally be stable, but some bugs may slip in. We recommend using the beta build primarily to test out new features and to verify bug fixes.

+
+## Demo
+
+Xterm.js ships with a barebones demo implementation, designed for the development and evaluation of the library only. Exposing the demo to the public as is would introduce security risks for the host.
+
+Below you can find instructions on how to run the demo on different platforms.
+
+### SourceLair
+
+SourceLair will run the demo and builder in parallel automatically. Just make sure to choose the "Node.js" project type, when cloning the xterm.js repo (or just use this shortcut; https://lair.io/xtermjs/xtermjs).
+
+Then open your project's [Public URL](https://help.sourcelair.com/projects/the-public-url/) to access the demo.
+
+### Docker
+
+First, make sure you have Docker Engine 1.13.0 (or newer) and Docker Compose 1.10.0 (or newer).
+
+Xterm.js [provides a pre-built Docker image](https://hub.docker.com/r/xtermjs/xterm.js/) to help run the demo easily (Git tags are built as [tagged Docker images](https://hub.docker.com/r/xtermjs/xterm.js/tags/) too).
+
+To run the just demo (with no editing access). run the following command in your terminal:
+
+```
+docker run -p 3000:3000 xtermjs/xterm.js
+```
+
+Then open http://0.0.0.0:3000 in a web browser to access the demo.
+
+To run the demo and builder in parallel, run the following command in your terminal:
+
+```
+docker-compose up
+```
+
+Then open http://0.0.0.0:3000 in a web browser to access the demo. If you prefer a different port than `3000` to access the xterm.js demo, then set the `XTERMJS_PORT` environment variable to the desired port.
+
+### Foreman (or other Procfile runner)
+
+First, be sure that a C++ compiler such as GCC-C++ or Clang is installed, then run the following commands in your terminal:
+
+```
+npm install
+foreman start  # Replace foreman with "honcho", "forego" etc. depending on your runner
+```
+
+Then open http://0.0.0.0:3000 in a web browser to access the demo.
+
+### Linux or macOS
+
+First, be sure that a C++ compiler such as GCC-C++ or Clang is installed, then run the following commands in your terminal:
+
+```
+npm install
+npm start      # Run this in its own terminal
+npm run watch  # Run this in its own terminal
+```
+
+Then open http://0.0.0.0:3000 in a web browser to access the demo.
+
+### Windows
+
+First, ensure [node-gyp](https://github.com/nodejs/node-gyp) is installed and configured correctly, then run the following commands in your terminal:
+
+```
+npm install
+npm start      # Run this in its own terminal
+npm run watch  # Run this in its own terminal
+```
+
+Then open http://127.0.0.1:3000 in a web browser to access the demo.
+
+*Note: Do not use ConEmu, as it seems to break the demo for some reason.*
+
+## Testing
+
+Tests are run using the following npm scripts:
+
+- `npm test`: This will run both unit tests and the linter
+- `npm run test-suite <file>`: This will run all tests within a particular file, &lt;file&gt; is the test file name excluding the extension (eg. "Linkifier.test")
+- `npm run test-debug`: This will run unit tests with `--inspect-brk`, this can then be automatically debugged using [VS Code auto attach](https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_auto-attach-feature) or manually attached to by a debugger
+- `npm run test-coverage`: This will run all unit tests and produce a coverage report
+- `npm run lint`: This will run the linter only
+
+## 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.
+
+### Code structure
+
+`src/` is roughly split up into areas of functionality such as `renderer/` that handles all rendering and `utils/` which provides general utility functions. The `shared/` folder contains code that can be used from either the main thread or a web worker thread, all code inside a `shared/` folder should only ever import other code from a `shared/` folder to minimize the amount of code ran when launching a web worker.

-## xterm-addon-canvas
-
-An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables a canvas-based renderer using a 2d context to draw. This addon requires xterm.js v5+.
-
-The purpose of this addon is to be used as a fallback for the [webgl addon](https://www.npmjs.com/package/xterm-addon-webgl) when better performance is desired over the default DOM renderer, but WebGL2 isn't supported or performant for some reason.
-
-### Install
-
-```bash
-npm install --save xterm-addon-canvas
-```
-
-### Usage
-
-```ts
-import { Terminal } from 'xterm';
-import { CanvasAddon } from 'xterm-addon-canvas';
-
-const terminal = new Terminal();
-terminal.open(element);
-terminal.loadAddon(new CanvasAddon());
-```
-
-See the full [API](https://github.com/xtermjs/xterm.js/blob/master/addons/xterm-addon-canvas/typings/xterm-addon-canvas.d.ts) for more advanced usage.

-## xterm-addon-ligatures
-
-Add support for programming ligatures to [xterm.js] when running in environments with access to [Node.js] APIs (such as [Electron]).
-
-### Requirements
-
- * [Node.js] 8.x or higher (present in [Electron] 1.8.3 or higher)
- * [xterm.js] 4.0.0 or higher using the default canvas renderer
-
-### Install
-
-```bash
-npm install --save xterm-addon-ligatures
-```
-
-### Usage
-
-```ts
-import { Terminal } from 'xterm';
-import { LigaturesAddon } from 'xterm-addon-ligatures';
-
-const terminal = new Terminal();
-const ligaturesAddon = new LigaturesAddon();
-terminal.open(containerElement);
-terminal.loadAddon(ligaturesAddon);
-```
-
-### How It Works
-
-In a browser environment, font ligature information is read directly by the web browser and used to render text correctly without any intervention from the developer. As of version 3, xterm.js uses the canvas to render characters individually, resulting in a significant performance boost. However, this means that it can no longer lean on the browser to determine when to draw font ligatures.
-
-This package locates the font file on disk for the font currently in use by the terminal and parses the ligature information out of it (via the [font-ligatures] package). As text is rendered in xterm.js, this package annotates it with the locations of ligatures, allowing xterm.js to render it correctly.
-
-Since this package depends on being able to find and resolve a system font from disk, it has to have system access that isn't available in the web browser. As a result, this package is mainly useful in environments that combine browser and Node.js runtimes (such as [Electron]).
-
-### Fallback Ligatures
-
-When ligatures cannot be fetched from the environment, a set of "fallback" ligatures is used to get the most common ligatures working. These fallback ligatures can be customized with options passed to `LigatureAddon.constructor`.
-
-### Fonts
-
-This package makes use of the following fonts for testing:
-

-## xterm-addon-serialize
-
-An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables xterm.js to serialize a terminal framebuffer into string or html. This addon requires xterm.js v4+.
-
-⚠️ This is an experimental addon that is still under construction ⚠️
-
-### Install
-
-```bash
-npm install --save xterm-addon-serialize
-```
-
-### Usage
-
-```ts
-import { Terminal } from "xterm";
-import { SerializeAddon } from "xterm-addon-serialize";
-
-const terminal = new Terminal();
-const serializeAddon = new SerializeAddon();
-terminal.loadAddon(serializeAddon);
-
-terminal.write("something...", () => {
-  console.log(serializeAddon.serialize());
-});
-```
-
-See the full [API](https://github.com/xtermjs/xterm.js/blob/master/addons/xterm-addon-serialize/typings/xterm-addon-serialize.d.ts) for more advanced usage.
-
-### Benchmark
-
-⚠️ Ensure you have `lolcat`, `hexdump` programs installed in your computer
-
-```shell
-$ git clone https://github.com/xtermjs/xterm.js.git
-$ cd xterm.js
-$ yarn
-$ cd addons/xterm-addon-serialize
-$ yarn benchmark && yarn benchmark-baseline
-$ # change some code in `xterm-addon-serialize`
