+roslibjs Build Setup
+====================
+
+[Grunt](http://gruntjs.com/) is used for building, including concatenating, minimizing, documenting, linting, and testing.
+
+### Install Grunt and its Dependencies
+
+ 1. Install [Node.js](http://nodejs.org/) for your environment
+ 2. Install the build task runner, [Grunt](http://gruntjs.com/)
+ 	```sh
+	$ [sudo] npm install -g grunt
+ 	```
+ 3. Install the [Cario](http://cairographics.org/) graphics library
+ 	- [System specific instaructions](https://github.com/Automattic/node-canvas/wiki/_pages)
+ 4. Install the dependencies and build dependencies
+	```sh
+	$ cd /path/to/roslibjs/
+   	$ [sudo] npm install
+	```
+
+### Build with Grunt
+
+Before proceeding, please confirm you have installed the dependencies above.
+
+To run the build tasks:
+
+ 1. `cd /path/to/roslibjs/`
+ 2. `grunt build`
+
+`grunt build` will concatenate and minimize the files under src and replace roslib.js and roslib.min.js in the build directory. It will also run the linter and test cases. This is what [Travis CI](https://travis-ci.org/RobotWebTools/roslibjs) runs when a Pull Request is submitted.
+
+`grunt dev` will watch for any changes to any of the src/ files and automatically concatenate and minimize the files. This is ideal for those developing as you should only have to run `grunt dev` once.
+
+`grunt doc` will rebuild all JSDoc for the project.
