 - before any key was pressed show the `Nothing was pressed yet` message;
 - when a key is pressed show a `The last pressed key is [key]` message;
 - use `componentDidMount` to add `keyup` handler:
-    ```ts
-    // DON'T import KeyboardEvent from React, because it is a regular event
-    document.addEventListener('keyup', (event: KeyboardEvent) => {
-      console.log(event.key);
-    });

+  // DON'T import KeyboardEvent from React, because it is a regular event
+  document.addEventListener('keyup', (event: KeyboardEvent) => {
+    console.log(event.key);
+  });
+  ```
 - use `removeEventListener` to remove a global handler in `componentWillUnmount`.
 
 ## Instructions
+
 - Install Prettier Extention and use this [VSCode settings](https://mate-academy.github.io/fe-program/tools/vscode/settings.json) to enable format on save.
 - Implement a solution following the [React task guideline](https://github.com/mate-academy/react_task-guideline#react-tasks-guideline).
 - Use the [React TypeScript cheat sheet](https://mate-academy.github.io/fe-program/js/extra/react-typescript).
 - Open one more terminal and run tests with `npm test` to ensure your solution is correct.
