-This API is simply a proxy to add a new language to [Prism](http://prismjs.com/) itself (the code highlighter). The `options` parameter must be the same accepted in Prism. You can read more about it [here](http://prismjs.com/extending.html#language-definitions).
-
-By default, codecup supports the following languages (which are also the default supported in Prism):
-
-- Markup (HTML/XML);
-- CSS;
-- C-like;
-- JavaScript;
-
-### Adding your own theme to codecup
-
-By default, codecup comes with a simple theme made from scratch called **[CodeNoon](https://github.com/kazzkiq/codecup.js/blob/master/src/styles/theme-default.js)**.
-
-You can easily override this theme with your own by writting your own CSS and adding it to your project. If that's the case, you should also disable **CodeNoon** with the `defaultTheme` option:
-
-```js
-import codecup from 'codecup';
-
-const cup = new codecup('#my-selector', {
-  language: 'js',
-  defaultTheme: false
-});
+cup.updateLanguage('javascript');
 ```

-# Credits & Thanks
-
-codecup.js was made possible by awesome open-source projects such as [Prism.js](https://github.com/PrismJS/prism) and [Webpack](https://github.com/webpack).
