problem with virtual and real subdomains

[rout3rx]

Hi,
i road this topic around : Virtual Subdomains (Wildcard) vs. real Subdomains
http://forum.parallels.com/showthread.php?t=111215
but not understand some sentence like:

4. I copied all lines between <VirtualHost [your IP address]> and </VirtualHost> to a new file I called zzz-wildcard.conf.

5. I changed the line "ServerAlias www.yourdomain.com" to "ServerAlias *.yourdomain.com".

6. I transferred the zzz-wildcard file to /etc/httpd/conf.d at my server.

can anyone help me and guide me step by step?
or is there any document or guideline with clear explain?
thanks
