##How to Start a New Game

1. Download the code from Cocos2d download site
2. Run setup.py
3. Run the cocos script

Example:

$ cd cocos2d-js
$ ./setup.py
$ source FILE_TO_SAVE_SYSTEM_VARIABLE

$ cocos new MyGame -l js -d /directory/to/project
$ cd /directory/to/project/MyGame

###Run the project under the game directory

• Run Cocos2d-html5 project with a Websever:

   cocos run -p web
  

• Compile and run project in Cocos2d-JSB :

   cocos compile -p ios|mac|android|web
   cocos run -p ios|mac|android|web
  

You may need to provide your NDK, Android SDK and ANT's path during the setup. Note that this tool is developed with python, so you will need python (32bit) 2.7.5 or later installed on your machine (but it doesn't support Python3). Please refer to Cocos Console document.

And if you have any doubt about the usage, please use -h with any command to have some help messages.

You can also use prebuilt Xcode or Visual Studio project which is located in Game/frameworks/runtime-src/proj.xxx
