 Xterm.js is a front-end component written in TypeScript that lets applications bring fully-featured terminals to their users in the browser. It's used by popular projects such as VS Code, Hyper and Theia.
 
 ## 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.

 ### 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 the [public API](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts).
 
-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
-```
-
-Then import the addon, instantiate it and call `Terminal.loadAddon`:
-
-```ts
+```javascript
 import { Terminal } from 'xterm';
-import { WebLinksAddon } from 'xterm-addon-web-links';
+import * as fit from 'xterm/lib/addons/fit/fit';
 
-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());
+Terminal.applyAddon(fit);
+
+var xterm = new Terminal();  // Instantiate the terminal
+xterm.fit();                 // Use the `fit` method, provided by the `fit` addon
 ```
 
-The xterm.js team maintains the following addons, but anyone can build them:
+You will also need to include the addon's CSS file if it has one in the folder.
 
-- [`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
+#### 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. `(xterm as any).fit()`. Alternatively, you can import the addon function and enhance the terminal on demand. This has better typing support and is friendly to treeshaking.
+
+```typescript
+import { Terminal } from 'xterm';
+import { fit } from 'xterm/lib/addons/fit/fit';
+const xterm = new Terminal();
+
+fit(xterm);  // Fit the terminal when necessary
+```
 
 ## 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.
+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
 
 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.

-## 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`
-$ yarn benchmark-eval
-```
