-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of experience,
-education, socio-economic status, nationality, personal appearance, race,
-religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-  advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting [@Tyriar](https://twitter.com/Tyriar) or [@pariskasid](https://twitter.com/pariskasid) on Twitter. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of an incident.
-Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.

+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 support can be turned on using the `screenReaderMode` option.
- **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 they can be built by anyone:

 ## 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:

-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.
+- Chrome latest
+- Edge latest
+- Firefox latest
+- Safari latest
+- IE11

-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.
+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
+
+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.*

 ## 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).
+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).

-### Beta builds
+## Development and Contribution

-Our CI releases beta builds to npm for every change that goes into master, install the latest beta build with:
+Xterm.js is maintained by [SourceLair](https://www.sourcelair.com/) and a few external contributors, but we would love to receive contributions from everyone!

-```
-npm install -S xterm@beta
-```
+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.

-These should generally be stable but some bugs may slip in, we recommend using the beta build primarily to test out new features and for verifying bug fixes.
+### Code structure

-## Contributing
-
-You can read the [guide on the wiki](https://github.com/xtermjs/xterm.js/wiki/Contributing) to learn how to contribute and setup xterm.js for development.
+`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 run what launching a web worker.
