It is explained in the next paragraph what "npx" is:

> Yep. cool? “npx” allows you to run a temporary package, which will be deleted right after each use. Use this command to try and experience how Fine works. Doesn’t hurt to try, huh?

It's not a satisfactory explanation for the layman, because it still assumes that you know that a package refers to something on npm, and that npx itself is a part of Node/npm.

All it would really need to say is that it requires a recent version of Node.
