How to use Semantic UI's theming in Semantic UI React?

The theming part is "missing" in the react semantic ui docs, but thats on purpose.

Thats the way I did it:

Install the full Semantic UI package. Semantic UI includes Gulp build tools so your project can preserve its own theme changes, allowing you to customise the style variables.

Detailed documentation on theming in Semantic UI is provided here.

$ npm install semantic-ui --save-dev

After building the project with Gulp, you'll need to include the minified CSS file in your index.js file:

import '../semantic/dist/semantic.min.css';

There are already different ui-frameworks with a more "react" approach. IMHO what semantic ui (react) does is the best real-live solution so far...
