#CodeCombat
[](https://travis-ci.org/codecombat/codecombat) CodeCombat is a multiplayer programming game for learning how to code. **See the [Archmage (coder) developer wiki](https://github.com/codecombat/codecombat/wiki/Archmage-Home) for a dev setup guide, extensive documentation, and much more. Every new person that wants to start contributing the project coding should start there.** It's both a startup and a community project, completely open source under the [MIT and Creative Commons licenses](http://codecombat.com/legal). It's the largest open source [CoffeeScript](http://coffeescript.org/) project by lines of code, and since it's a game (with [really cool tech](https://github.com/codecombat/codecombat/wiki/Third-party-software-and-services)), it's really fun to hack on. Join us in teaching the world to code! Your contribution will go on to show millions of players how cool programming can be. ### [Getting Started](https://github.com/codecombat/codecombat/wiki/Dev-Setup:-General-Information) We've made it easy to fork the project, run a simple script that'll install all the dependencies, and get a local copy of CodeCombat running right away on [Mac](https://github.com/codecombat/codecombat/wiki/Dev-Setup:-Mac-and-Vagrant), [Linux](https://github.com/codecombat/codecombat/wiki/Dev-Setup:-Linux), or [Windows](https://github.com/codecombat/codecombat/wiki/Dev-Setup:-Windows).
