CNAME/A record setup

A previous poster said:

I think that we should be able to add a CNAME/A record to our domain to point it here, instead of changing our nameservers. It would be very nice to have this, considering that would let us still have full management of our domain but also be able to use InfinityFree without changing nameservers.

Is this a way to do that?

I was going to link to that article, it should answer every part of your question.
