mathjs/CONTRIBUTING.md

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices.

## Contributing

Contributions to the math.js library are very welcome! We can't do this alone.
You can contribute in different ways: spread the word, report bugs, come up with
ideas and suggestions, and contribute to the code.

There are a few preferences regarding code contributions:

- Math.js follows the node.js code style as described
  [here](http://nodeguide.com/style.html).
- Send pull requests to the `develop` branch, not the `master` branch.
- Only commit changes done in the source files under `lib`, not to the builds
  which are located in the folder `dist`.

Thanks!
