Maybe wrong documentation ?

I decided to use paseto and I starting to read the docs but this seems to have an error

https://github.com/paragonie/paseto/tree/master/docs

php

/**
 * @var SymmetricKey $sharedKey
 */
$token = Builder::getLocal($sharedKey, new Version2());

$token = (new Builder())
    ->setKey($sharedKey)
....

in fact is missing the variable

$sharedKey = new SymmetricKey(random_bytes(32));

in both example
