The beginning assumes too much knowledge of terminal "npx" and installing nvm and updating node etc.
Explore the project section is unordered list, but instead use code like this to show file structure:
| node_modueles
| public
|-.gitignore
Make sure to use triple ticks to make new lines of code, e.g. here ReactDOM.render(<App />, document.getElementById('root'));
No explanation of webpack or transpiling before you just jump into them. Needs more definition, explanation.
I followed chapter one exactly and it did not work because my create-react-app was out of date. Put step to install or add create-react-app using npm. Once I updated it worked.
ReactDOM.render(<App />, document.getElementById('root'));
