To set up Redux Toolkit (RTK) in a React project, you install the required packages, create a slice, configure the store, and connect it to your React components using React-Redux hooks.
Install dependencies: npm install @reduxjs/toolkit react-redux
Create a slice using createSlice for your state and reducers.
Configure the store using configureStore and add your slices as reducers.
Wrap your app with <Provider store={store}> in index.js.
Use useSelector to read state and useDispatch to trigger actions in your components.
