Also see the [Rendering](https://github.com/liabru/matter-js/wiki/Rendering) wiki page, which also shows how to use your own game loop. ### 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](http://codepen.io/collection/Fuagy/). ### Documentation See the [API Documentation](http://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](http://nodejs.org/) and [gulp](http://gulpjs.com/), then run npm install This will install the required build dependencies, then run gulp 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)](http://opensource.org/licenses/MIT) Copyright (c) 2014 Liam Brummitt This license is also supplied with the release and source code.
