My advice is to send out the rules you want to follow to your players via email. I would also suggest a "session 0" for character creation where stats are generated in front of you. More effective might be to have a bunch of session 0 opportunities where you can walk through creating a PC with your players one-on-one... important if you have new people so you can dedicate your attention to them.
I have a special process for character creation which differs depending on what each player wants to make, so a dedicated session often works better... plus you can keep character stats private this way between you, the CK, and the player in question.
TL;DR there's no right way or wrong way to do this - you have to pick what you want to do as the CK.
