registration (signup) form custom fields

Hi there…

I’ve been struggling for a week trying to find how to customize the user registration form. I’m using Jobify theme and in the signup page, it calls shortcake [jobify_register_form]. I don’t find where I can add fields to registration form, which will be saved in the user database and retrieve when the user will display his/her profile…

Any help would be really appreciated!!

Thanks
