+Different distribution flavours are available in the `dist` directory:
+
+* **amd:** For [RequireJS](http://requirejs.org/)
+* **common-js:** For [NodeJS](https://nodejs.org/)-like ecosystems
+* **es6:** For [Babel](http://babeljs.io/), or whenever ES6 becomes universally supported by browsers.
+* **raw:** Compressed and uncompressed ES5 versions, the latter of which is also available in `src`.
+
+The base stylesheet is located at `src/accordion.css`.
+Feel free to embed it into your application's existing styling, tweaking it if desired.
