Custom field to the registration page

Hello,

I am trying to customize the registration page, I need to insert more questions for the user to answer, I have already asked in openEdx, but never using the tutor. I wonder if anyone else has done this and where can I start.

thanks.

This is documented here:
https://edx.readthedocs.io/projects/edx-installing-configuring-and-running/en/latest/configuration/customize_registration_page.html

Thanks, I thought that maybe there was another way.
