Feel free to change the wording, or completely disregard. I won't be offended :)

Thank you for making and sharing this, I really appreciate it.

This is a great suggestion! I'd only add the fact that npx assumes a modern version of npm: >=5.2.0, which comes bundled with node >= 8.
Just to cover the case of someone trying to use npx in an ancient environment.

CRA has a similar suggestion here: https://github.com/facebook/create-react-app#quick-overview
These should be roughly equivalent.

yarn instructions are also missing - one-liner is:

yarn create react-app my-app --scripts-version=react-scripts-ts

It's similar in npm now: npm create react-app my-app --scripts-version=react-scripts-ts
