Contributions and pull requests are very welcome. Please follow these guidelines when submitting new code.

1. Make all changes in Coffeescript files, not JavaScript files.
2. For feature changes, update both jQuery and Prototype versions
3. Use npm install -d to install the correct development dependencies.
4. Use cake build or cake watch to generate Chosen's JavaScript file and minified version.
5. Don't touch the VERSION file
6. Submit a Pull Request using GitHub.

First, make sure you have the proper CoffeeScript / Cake set-up in place. We have added a package.json that makes this easy:

npm install -d

This will install coffee-script and uglifyjs.

Once you're configured, building the JavasScript from the command line is easy:

cake build                # build Chosen from source
cake watch                # watch coffee/ for changes and build Chosen

If you're interested, you can find the recipes in Cakefile.
