Mins is a Primer child theme with a minimal design

I was in the process of creating a child theme of the Mins theme and while viewing the current style.css in the Mins directory I read this in the description:

  • Description: Mins is a Primer child theme with a minimal design.

Does this mean if I stay with Mins I do not have to create a Child Theme like described at this link?

I would like to just continue with what I have if not needed. Since I have made some code changes I would like to never have to worry about starting over when I update the Mins theme.

If it is not the case I will be back with more questions.
