I am attempting to setup Secondary dns with a well known provider. The goal is to have DNS served from 2 providers. The secondary DNS provider will mirror records from the primary dns provider so I only have to update them in one place.
I am reading through their instructions and need clarification.

I am assuming this means on the current DNS's provider I add the records to their dns zone/system file. If I do this ahead of time will this cause any downtime/issues? Or is this is simply a pointer record?
Step 2 is:
Add our name servers, as listed above, to the delegation of your domain through your registrar
Does this mean I go to my domain register and add their name servers to the end of my name servers like what I did for my primary DNS provider?
