Lack of more examples on the README

[Kazbonfim]

I was studying right now, and i've noticed that the oficial doc don't have the same lines that my professor is using - and i am thinking, why this? There is a different session i've not gon' through?

The lines where:
`const readline = require('readline').createInterface({
input: process.stdin,
output: process.stdout,
});

readline.question("Qual a sua linguagem preferida? ", (language) => {
console.log(A minha linguagem preferida é: ${language});
readline.close()
});
`
