How setup CWP on subdomains

I have a domain to be used for subdomains, for ex. www.subDomain1.mainDomain.com, www.subDomain2.mainDomain.com, and so on. I need a separate CWP for each one of those domains. I ask, how should I proceed? Thank you!

www. is a subdomain in its' own right. It is now pretty antiquated and can/should be ignored; a CNAME record can be used for those who persist in its' use.
Create 2 new accounts:
subDomain1.mainDomain.com and
subDomain2.mainDomain.com
This gives you independent and isolated domains. These can share the same IP address.
Just remember to add in the appropriate DNS entries.

Thank you Cynique.
Unfortunately I am not expert and would also appreciate if you can guide me to add in the appropriate DNS entries. Where should I go and what should I do? Thank you again !  :-)
