+# Chosen
+
+Chosen is a library for making long, unwieldy select boxes more user friendly.
+
+- jQuery support: 1.4+
+- Prototype support: 1.7+
+
+For documentation, usage, and examples, see:  
+http://harvesthq.github.com/chosen
+
+### Contributing to Chosen
+
+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.
+
+### Using CoffeeScript & Cake
+
+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.
+
