Hi, jervino1960,

Have you read the Wordpress documentation?

Wordpress is a high-end professional product. I am not a Wordpress person, but I would think that very complete “how to use Wordpress” information would be found in their documentation. It would not be to their advantage to skimp on the user instructions.
