+- Supports all Font Awesome modifiers (see [API](#API) below).
 - Add your own `className`s, styles and other props (all additional props are passed directly to the component).
 - Standard, non-ES6 JavaScript, so should work most places without a build step.
     - Packaged as a CommonJS/npm module.
