We will create a new project using the `react-redux` template. Open the console and `cd` into an appropriate location, then create a new project using the command: `npx create-react-app post-app --template redux`.

Now that the project is set up, we need to remove the default counter application and delete everything in the `src` folder.

We will create a new `index.js` file containing the following base code:

```js
import React from 'react';
import { createRoot } from 'react-dom/client';
import { Provider } from 'react-redux';
import { store } from './app/store';
 
const container = document.getElementById('root');
const root = createRoot(container);
 
function Main(props) {
  return (<h1>Hello World</h1>);
}
 
root.render(
  <React.StrictMode>
    <Provider store={store}>
      <Main />
    </Provider>
  </React.StrictMode>
);
```

Since we are also importing a store, we will create a new `store.js` in a new app folder:

```js
import { configureStore } from '@reduxjs/toolkit';
export const store = configureStore({
  reducer: {},
});
```

Now we can run the app to see a `'Hello World'` screen:

However, this is only a setup, there's more to do! 

Which component is the entry point of this React application?

In this section we will learn what Redux is, why it is useful, and most importantly when it is useful. We will also learn how to set up a basic react-redux application.

In this section we will go through the fundamental concepts of Redux that are necessary to understand the workings of a Redux application. We will use code examples to understand the concepts and in the following section we will use them practically.

In the previous section we looked at the basic concepts. In this section we use those basic concepts to understand some more complicated concepts and the structure of a Redux application. In the end we will also look at the Counter application to put together all the pieces of our knowledge together.

This chapter is focused on practice hence we will utilize the knowledge we acquired in previous sections to create a practical application using Redux along with React.
