+## Filing an issue
+
+Before filing an issue, please [search the queue](https://github.com/c3js/c3/issues) to make sure it hasn't already been reported.
+
+If a bug, please include the following —
+
+1. What version of C3?
+1. What browsers have you confirmed it in?
+1. Can you isolate the issue by providing a jsFiddle demonstrating it in a minimalist capacity?
+
+Please *do not* ask for support using the issue queue. For support, please ask [on chat](https://gitter.im/c3js/c3) or [the mailing list](groups.google.com/forum/#!forum/c3js).
+
+## Setup
+ 1. **Clone the repo from GitHub**
+
+ git clone https://github.com/c3js/c3.git
+ cd c3
+
+ 2. **Acquire build dependencies.** Make sure you have [Node.js](http://nodejs.org/) installed on your workstation. This is only needed to _build_ C3 from sources. C3 itself has no dependency on Node.js once it is built. Now run:
+
+ npm install -g grunt-cli
+ npm install
+
+ The first `npm` command sets up the popular [Grunt](http://gruntjs.com/) build tool. You might need to run this command with `sudo` if you're on Linux or Mac OS X, or in an Administrator command prompt on Windows. The second `npm` command fetches the remaining build dependencies.
+
+## Building C3 from sources
+ npm run build
+
+
+## Distribution
+ npm run dist
+
+Now you'll find the built files in `c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`.
+
+## Running the tests
+ npm run test
+
+This command will automatically run the specification suite and report its results.
+
+If you want to see specs running live in browser (e.g., for debugging), simply open `http://localhost:9876/` in your browser when phantomjs starts.
+
+## Contributing your changes
+
+Add something about PRs here, indicate that PRs should not bump the version number & the build output files (`c3.js`, `c3.min.js`, `c3.css` & `c3.min.css`) should be excluded
