$ yarn build // production build

In src/index.js

There is an object called const VISIBLE = {}; with a list of all examples, all you have to do is, to see a particular example. Let's say you want to see react-spring examples of hooks, do the following in your App state

state = {
    isVisible: [
      VISIBLE.IS_REACT_SPRING_1_VISIBLE,
      VISIBLE.IS_REACT_SPRING_2_VISIBLE,
    ],
};

And that's pretty much it, just add a VISIBLE.SOME_EXMAPLE to your isVisible state array, your app will hot reload with the new UI information.
