More documentation is required

[msolla-ligno]

Hello. I'm considering adding this library to my projects, but there are a couple of issues I don't see addressed in the documentation:

• The project where I want to add the library is new, but the database is shared with other websites that have been running for years, and we can't change it too much. Is there a way to specify the existing tables and columns that the library should use to handle authentication?
• An essential requirement is that authentication generates an authentication token. This token should contain specific information that we need to customize. Does this library allow for this? If so, how would I go about it?

As an extra comment, I think more documentation is required, for example how install and starting to use the library, requerimens, database structure needed, etc.

Thank you.
