Also see the [Running](https://github.com/liabru/matter-js/wiki/Running) and [Rendering](https://github.com/liabru/matter-js/wiki/Rendering) wiki pages, which show how to use your own game and rendering loops. ### Tutorials See the list of [tutorials](https://github.com/liabru/matter-js/wiki/Tutorials). ### Examples See the [examples](https://github.com/liabru/matter-js/tree/master/examples) directory which contains the source for all [demos](#demos). There are even more examples on [codepen](https://codepen.io/collection/Fuagy/). ### Plugins The engine can be extended through plugins, see these resources: - [Using plugins](https://github.com/liabru/matter-js/wiki/Using-plugins) - [Creating plugins](https://github.com/liabru/matter-js/wiki/Creating-plugins) - [List of plugins](https://github.com/liabru/matter-js/wiki/List-of-plugins) - [matter-plugin-boilerplate](https://github.com/liabru/matter-plugin-boilerplate) ### Documentation See the [API Documentation](https://brm.io/matter-js/docs/) and the [wiki](https://github.com/liabru/matter-js/wiki) ### Building and Contributing To build you must first install [node.js](https://nodejs.org/), then run npm install This will install the required build dependencies, then run npm run dev to spawn a development server. For information on contributing see [CONTRIBUTING.md](https://github.com/liabru/matter-js/blob/master/CONTRIBUTING.md). ### Changelog To see what's new or changed in the latest version, see the [changelog](https://github.com/liabru/matter-js/blob/master/CHANGELOG.md). ### References See the wiki page on [References](https://github.com/liabru/matter-js/wiki/References). ### License Matter.js is licensed under [The MIT License (MIT)](https://opensource.org/licenses/MIT) Copyright (c) 2014 Liam Brummitt This license is also supplied with the release and source code.
