-# React ToDo App
-
-Implement a simple [TODO app](https://mate-academy.github.io/react_todo-app/) that functions as described below.
-
-> If you are unsure about how a feature should work, open the real TodoApp and observe its behavior.
-
-![todoapp](./description/todoapp.gif)
-
-1. Learn the markup in `App.tsx`.
-2. Show only a field to create a new todo if there are no todos yet.
-3. Use React Context to manage todos.
-4. Each todo should have an `id` (you can use `+new Date()`), a `title`, and a `completed` status (`false` by default).
-5. Save `todos` to `localStorage` using `JSON.stringify` after each change.
-6. Display the number of not completed todos in `TodoApp`.
-7. Implement filtering by status (`All`/`Active`/`Completed`).
-8. Add the ability to delete a todo using the `x` button.
-9. Implement the `clearCompleted` button (disabled if there are no completed todos).
-10. Implement individual todo status toggling.
-11. Implement the `toggleAll` checkbox (checked only when all todos are completed).
-12. Enable inline editing for the `TodoItem`:
-    - Double-clicking on the todo title shows a text field instead of the title and `deleteButton`.
-    - Form submission saves changes (press `Enter` to save).
-    - Trim the saved text.
-    - Delete the todo if the title is empty.
-    - Save changes `onBlur`.
-    - Pressing `Escape` cancels editing (use `onKeyUp` and check if `event.key === 'Escape'`).

-## Instructions
-
-- Install the Prettier Extension and use these [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 guidelines](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 another terminal and run tests with `npm test` to ensure your solution is correct.
-- Replace `<your_account>` with your GitHub username in the [DEMO LINK](https://<your_account>.github.io/react_todo-app/) and add it to the PR description.
