Profile holds your own account details: name, email, and the role(s) assigned to your account.
Editing your profile
Edit Profile opens the Update Profile form, where you can change your First Name and Last Name. Email is your account's sign-in address, and Roles shows your assigned role (Admin or Buyer), see the Users module if you need someone's role changed, that's an Admin-only action there, not something you set for yourself.
