The default project already contains a counter application. However, we would like to create our application, so we need to modify the template. 

- Delete everything inside the `src` folder, excluding the `app` folder;
- Delete the `store.js` file inside the `app` folder.

The resultant should look like this kind of empty structure:

- `src`
  - `app`

We won't use the `features` folder in this section. However, organizing the components and their reducers in the `features` is recommended when working on bigger projects.

What files or folders are safe to delete from the Redux template?

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.
