Please add documentation

Describe the feature
As the title suggests could you do some documentation

How do we get the json object so i can save a string of the fingerprint and reuse for future sessions
Before it was something like this:
var fingerprint = fingerprintGenerator.getFingerprint({ 'locales': ['en-US'], // setup your desired fingerprint features 'operatingSystems': ['linux'], });
await fingerprintInjector.attachFingerprintToPuppeteer(page, fingerprint);
and could you maybe put some intergration examples in the crawlee docs aswell.
It would be nice if there was an example of crawlee + stealth addon + fingerprint saving and loading
