How to be a Vib Sephora member?

Could you please elaborate on the steps required to become a Vib Sephora member? I understand that it's a membership program offering exclusive benefits and privileges, but I'm unsure of the exact process. Do I need to make a purchase to qualify? Is there a specific criteria or conditions that I must meet? I'm particularly interested in knowing how to sign up and what kind of perks I can expect as a member.
