+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`, this includes support for curses-based apps and mouse event support.
- **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 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:
-
-```bash
-npm i -S xterm-addon-web-links
-```
-
-Then import the addon, instantiate it and call `Terminal.loadAddon`:
-
-```ts
-import { Terminal } from 'xterm';
-import { WebLinksAddon } from 'xterm-addon-web-links';
-
-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());
-```
-
-The xterm.js team maintains the following addons but they can be built by anyone:
-
- [`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
-
-## 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*.
-
-We also partially support *Intenet Explorer 11*, meaning xterm.js should work for the most part, but we reserve the right to not provide workarounds specifically for it unless it's absolutely necessary to get the basic input/output flow working.
-
-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.
-
-## API
+### 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.

+
+### Addons
+
+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.
+
+To use an addon, just import the JavaScript module and pass it to `Terminal`'s `applyAddon` method:
+
+```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
+```
+
+You will also need to include the addon's CSS file if it has one in the folder.
+
+#### Importing Addons in TypeScript
+
+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 { fit } from 'xterm/lib/addons/fit/fit';
+const xterm = new Terminal();
+
+// Fit the terminal when necessary:
+fit(xterm);
+```
+
+#### Third party addons
+
+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. Here is a list of the versions we aim to support:
+
+- Chrome latest
+- Edge latest
+- Firefox latest
+- Safari latest
+- IE11
+
+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.
+
+## API
+
+The current full API documentation is available in the [TypeScript declaration file on the repository](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts), switch the tag (press `w` when viewing the file) to point at the specific version tag you're using.

-
-An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables fitting the terminal's dimensions to a containing element. This addon requires xterm.js v4+.
-
-### Install
-
-```bash
-npm install --save xterm-addon-fit
-```
-
-### Usage
-
-```ts
-import { Terminal } from 'xterm';
-import { FitAddon } from 'xterm-addon-fit';
-
-const terminal = new Terminal();
-const fitAddon = new FitAddon();
-terminal.loadAddon(fitAddon);
-terminal.open(containerElement);
-fitAddon.fit();
-```
